What I would actually book
A standard Balcony cabin is the sensible default on any of these six ships. Families and anyone wanting more space should price a Mini-Suite before assuming they need a full suite. If the Sky Suite specifically is the draw — two bedrooms, roughly 1,800 sq. ft., a flagship category Princess introduced with this class — you have to book Sky, Enchanted or Discovery Princess; the original trio doesn’t offer it at any price.
Balcony
The largest category on every ship in this class by a wide margin — roughly 715–753 cabins per ship depending on which generation.
Mini-Suite
Roughly 306–374 cabins per ship; price this before assuming you need a full suite.
Sky Suite
Two per ship, only on Sky, Enchanted and Discovery Princess — roughly 1,800 sq. ft. with two bedrooms, the largest stateroom category Princess has introduced on any ship in this research project.
Reserve Collection, not Sanctuary Collection
A private Concierge Lounge and Reserve Dining area exist on this class, but no dedicated suite-only restaurant the way Sanctuary Collection has on Sun and Star Princess.
A signature SeaWalk on every ship
A glass-floored walkway cantilevered out over the side of the ship — present fleet-wide across this entire class, per each ship’s own current Princess fact sheet.
Cabins near the theater or entertainment venues, below the pool deck, and obstructed-view balconies on the lower outside decks
The most consistently documented location patterns across this class — see the location section below.
Two generations, six ships, one class name
All six ships share the same core hull family and the same named-tier category system, but Princess built them in two distinct waves nearly a decade apart. The three-ship split below is the fastest way to know which generation you’re comparing.
Royal Princess (2013)
First of the class. 1,780 total guest staterooms per Princess’s current fact sheet (342 interior, 730 balcony, 358 deluxe balcony, 314 mini-suite, 36 suites). Two suite grades below the top tier — Owner’s Suite and Penthouse Suite — plus Premium Suite. No Sky Suite or Window Suite; those arrived with the later trio.
Regal Princess (2014)
Royal’s near-identical sister — same forward sunning platform, same dual-pool layout, same Sabatini’s placement. Princess’s current ship page and independent sources agree on 1,780 total staterooms (342 interior, 732 balcony, 360 deluxe balcony, 306 mini-suite, 40 suites); an older, cached Princess fact sheet for this ship states a stale 1,337 and should not be treated as current.
Majestic Princess (2017)
The most different ship in the original trio — built with the Asia-Pacific market specifically in mind, no aft pool, and dining substitutions (Hollywood Conservatory/Pool Club instead of a second Sanctuary-style deck area, a Cantonese-focused specialty restaurant). Same core 1,780-stateroom structure as her sisters (342 interior, 715 balcony, 313 deluxe balcony, 374 mini-suite, 36 suites) despite the public-space differences.
Sky Princess (2019)
First of the enlarged trio, and the ship that introduced the Sky Suite — two per ship, roughly 1,800 sq. ft. with two bedrooms, Princess’s largest stateroom category in this research project. 1,830 total guest staterooms per Princess’s current fact sheet (340 interior, 753 balcony, 311 deluxe balcony, 6 Premium Oceanview, 374 mini-suite, 44 suites with private balconies plus 2 Sky Suites). Current Princess brochure and deck-plan material also confirms a Window Suite (S7) grade on this ship — a no-balcony category the fact sheet doesn’t break out separately.
Enchanted Princess (2021)
Pandemic-delayed sister to Sky Princess, entering service about 18 months later than originally planned. Same 1,830-stateroom structure (340 interior, 753 balcony, 311 deluxe balcony, 6 oceanview, 374 mini-suite, 46 suites) and, like Sky Princess, carries a distinct Window Suite grade (2 per ship) alongside the Sky Suite, named specifically in this ship’s own materials. Added The Catch by Rudi, Princess’s first dedicated seafood specialty restaurant.
Discovery Princess (2022)
Newest of the six and the most accessible by cabin count — 40 wheelchair-accessible staterooms, more than any other ship in this class. Shares the same 1,830-stateroom structure as Sky and Enchanted Princess (340 interior, 753 balcony, 311 deluxe balcony, 6 oceanview, 374 mini-suite, 46 suites).
Interior → Balcony → Deluxe Balcony → Mini-Suite → Suite → Sky Suite
Like every current Princess class, Royal Class sells by named tier rather than a single numbered or lettered code — Interior, Balcony, Deluxe Balcony, Mini-Suite, Suite and (on the enlarged trio only) Sky Suite, with individual cabin grades lettered underneath each tier on the deck plan. This is a longer ladder than Coral Class runs, and on Sky, Enchanted and Discovery Princess specifically, it includes a small Oceanview rung the original trio skips entirely.
Two ship generations, two inventories
The category structure is close but not identical across the six ships, and it splits cleanly along generational lines. Both generational tables below reflect each ship’s own current Princess fact sheet — we did not force a single dataset to fit both.
Original trio — Royal, Regal, Majestic Princess
| Family | Category | Approx. size | Notes |
|---|---|---|---|
| Interior | Interior (IA–IF) | ~150–180 sq. ft. | 342 cabins on each of the three ships — no window |
| Balcony | Balcony (BA–BF, plus obstructed BV/BW/BY) | ~185–217 sq. ft. + balcony | The largest category on all three ships — 715–732 cabins depending on the ship, per each ship’s current fact sheet |
| Deluxe Balcony | Deluxe Balcony (DA–DF, D4, plus obstructed DV/DW) | ~217–232 sq. ft. + balcony | 313–360 cabins depending on the ship — a larger balcony cabin than standard, still short of Mini-Suite |
| Mini-Suite | Mini-Suite (MA–MF, plus Reserve Collection Mini-Suite M1/M6) | ~285–425 sq. ft. | 306–374 cabins depending on the ship — M1 is the Reserve Collection grade, bundled with Reserve Collection perks |
| Suite | Owner’s Suite (S2), Penthouse Suite (S3–S4), Premium Suite (S5) | ~470–800 sq. ft. | 36–40 suites total depending on the ship — no Sky Suite or Window Suite on this generation |
Enlarged trio — Sky, Enchanted, Discovery Princess
| Family | Category | Approx. size | Notes |
|---|---|---|---|
| Interior | Interior (IA–IF) | ~150–180 sq. ft. | 340 cabins on each of the three ships — no window |
| Oceanview | Premium Oceanview | ~150–180 sq. ft. | A small category the original trio doesn’t sell at all — 6 cabins on each of the three ships, window with no balcony |
| Balcony | Balcony (BA–BF, plus obstructed BV/BW/BY) | ~185–217 sq. ft. + balcony | The largest category on all three ships — 753 cabins on each |
| Deluxe Balcony | Deluxe Balcony (DA–DF, D4, DZ, plus obstructed DV/DW) | ~217–232 sq. ft. + balcony | 311 cabins on each ship |
| Mini-Suite | Mini-Suite (MA–MF, plus Reserve Collection Mini-Suite M1/M6) | ~285–425 sq. ft. | 374 cabins on each ship |
| Suite | Owner’s Suite (S2), Penthouse Suite (S3–S4), Premium Suite (S5) | ~470–800 sq. ft. | Each ship’s current fact sheet reports 42–44 suites with private balconies as a combined figure across these three grades — not independently broken out per grade |
| Suite | Window Suite (S7 on Sky Princess, per current Princess brochure and deck-plan material) | Not specified in the material we reviewed — no balcony | 2 per ship on all three ships in this generation. Princess doesn’t clearly state whether these cabins are counted inside the "suites with private balconies" figure above or sit outside it — we present both published facts rather than inventing a reconciliation |
| Sky Suite | Sky Suite (S0) | Roughly 1,800+ sq. ft., two bedrooms | Just 2 per ship — Princess’s flagship stateroom category, introduced with Sky Princess and unique to this three-ship generation |
An older, cached Princess fact sheet for Regal Princess states 1,337 total staterooms — a figure that doesn’t match Princess’s own current ship page or independent cabin-by-cabin sources, all of which agree on 1,780. We treat 1,780 as the current, authoritative figure here and flag the 1,337 figure as stale rather than repeating it as a live number.
Current Princess brochure and deck-plan material confirms a Window Suite (S7) grade on Sky Princess — a correction to this guide, which previously described Sky Princess as having only four suite grades and equated Princess’s "44 suites with private balconies" fact-sheet figure with "44 standard suites." Enchanted Princess names the same grade specifically in her own materials, and Discovery Princess’s published breakdown carries the same 2-cabin allotment. None of the three ships’ fact sheets clearly states how Window Suite cabins relate to the "suites with private balconies" total, so we present the figures side by side rather than forcing a reconciliation Princess itself hasn’t published.
Exact suite-grade-to-letter-code mapping (which specific code is Owner’s vs. Penthouse vs. Premium on each ship) is consistent across the sources we checked but wasn’t independently confirmed against each ship’s own Princess booking engine for every ship. Treat the S2/S3–S4/S5 code pattern as indicative of the general structure, not a booking-guaranteed mapping for a specific cabin.
The value baseline across all six ships
Interior cabins run roughly 150–180 sq. ft. across all six ships — genuinely windowless. The original trio carries 342 per ship; the enlarged trio carries 340 per ship, a difference too small to matter for booking purposes. This is the most consistent category across the entire class.
On Sky, Enchanted or Discovery Princess specifically, a small 6-cabin Oceanview category exists as a step up — it doesn’t exist at all on Royal, Regal or Majestic Princess, where Balcony is the next rung up from Interior.
A category that only exists on three of the six ships
This is the cleanest generational split in the whole class: Royal, Regal and Majestic Princess do not sell a standalone Oceanview category at all — Balcony is the next step up from Interior on those three ships. Sky, Enchanted and Discovery Princess each carry a small Premium Oceanview category — just 6 cabins per ship, a window with no private balcony.
If a standard Oceanview cabin (window, no balcony) is specifically what you’re shopping for, you need the enlarged trio — and even there, it’s a very small inventory (6 cabins per ship), so availability will be tight.
The default choice, with a genuine Deluxe step-up
Balcony is the largest category on every ship in this class — 715–753 cabins depending on the ship. Unlike Coral Class, this class also runs a distinct Deluxe Balcony tier above standard Balcony (roughly 217–232 sq. ft. versus 185–217 sq. ft.), a real size step rather than a marketing label, present on all six ships. Obstructed-view grades (BV, BW, BY on standard Balcony; DV, DW on Deluxe Balcony) sit at a lower price with a lifeboat or machinery obstruction, most commonly reported on the lower outside decks (Deck 8/Emerald Deck across the class).
The size step from standard to Deluxe Balcony is real but modest — worth pricing the gap directly rather than assuming Deluxe is automatically worth it for your itinerary.
A sitting-area step up, including a direct route into Reserve Collection
Mini-Suite runs roughly 285–425 sq. ft. depending on the ship, adding a sitting area over a Balcony cabin without full suite pricing. Inventory ranges from 306 (Regal Princess) to 374 (Majestic, Sky, Enchanted and Discovery Princess). One specific grade — M1, sometimes still labeled "Club Class Mini-Suite" on third-party booking aggregators — is Reserve Collection’s Mini-Suite tier: the same physical footprint as any other Mini-Suite, bundled with Reserve Collection perks at a fare below the full Suite tier.
A standard Mini-Suite
The sitting-area upgrade over a Balcony cabin, at a fare below the suite tiers — price this before assuming you need a full suite.
A Reserve Collection Mini-Suite (M1) specifically
The same physical footprint as a standard Mini-Suite, but bundled with Reserve Collection perks — confirm which specific cabins carry this designation before booking if those perks are the reason you’re shopping this category.
Three shared grades, plus a flagship category only three of the six ships have
All six ships share the same three-grade core suite structure: Owner’s Suite (the entry grade), Penthouse Suite, and Premium Suite. Each ship’s current fact sheet reports 36–40 suites with private balconies on the original trio and 42–44 on the enlarged trio, as a combined figure across those three grades. The real headline is the Sky Suite: introduced with Sky Princess in 2019 and carried onto Enchanted and Discovery Princess, it’s roughly 1,800+ sq. ft. with two bedrooms — described by outside coverage as Princess’s largest and most elaborate stateroom category to date. Just 2 exist per ship, and only on those three ships. All three enlarged-trio ships also carry a Window Suite grade — a no-balcony suite category, 2 per ship. Enchanted Princess names it specifically in her own materials; current Princess brochure and deck-plan material confirms it on Sky Princess as well, identifying it as code S7; Discovery Princess’s published breakdown carries the same 2-cabin allotment. None of the three ships’ fact sheets clearly states how Window Suite cabins relate to the "suites with private balconies" figure — we present both published facts rather than inventing a reconciliation.
It only exists on Sky, Enchanted and Discovery Princess — Royal, Regal and Majestic Princess do not offer it at any price, and with only 2 per ship even on the ships that have it, book well ahead.
A private lounge, but still no dedicated suite restaurant
Reserve Collection is Princess’s standard suite-tier program, used fleet-wide except on Sphere Class (which runs Sanctuary Collection instead). On Royal Class specifically it includes a private Concierge Lounge for suite guests (roughly 24-person capacity on Royal Princess, per Cruise Critic) in addition to the Reserve Dining area inside the main dining room, priority embarkation and disembarkation, a welcome bottle of wine or in-room mini-bar setup, evening canapés on request, and upgraded terry bathrobes. That Concierge Lounge is a real amenity Coral Class doesn’t have — but it still isn’t a separate, dedicated suite-only restaurant the way Sanctuary Collection delivers on Sun and Star Princess.
Sanctuary Collection on Sun and Star Princess includes a dedicated, suite-only restaurant, lounge and adults-only retreat deck. Reserve Collection on this class does not — Reserve Dining is a section of the main dining room, plus the Concierge Lounge described above, not a separate restaurant venue.
Six ships, six different current figures
Accessible-cabin counts genuinely differ by ship on this class rather than following one class-wide number — Princess’s own current sources put Royal Princess at 36, Regal Princess at 38, Majestic Princess at 38, Sky Princess at 38, Enchanted Princess at 38, and Discovery Princess at 40 (the highest of the six, and the newest ship). Regal and Enchanted Princess each have a secondary-source figure of 36 that conflicts with the Princess-published 38 — we treat Princess’s own current figures as authoritative and note the third-party conflict only where it exists.
Confirm the exact accessible cabin number, category and door width directly with Princess or a travel advisor well ahead of your sailing — and confirm which ship, since this is one of the few figures on this class that doesn’t generalize across all six.
The same handful of patterns, repeated across all six ships
The same general location risks turn up in cabin-selection research for every ship in this class — a byproduct of the shared hull family and deck layout. Exact cabin numbers differ ship to ship (and we could not independently verify every number for every ship), so treat the pattern below as class-general and check each ship’s own page for its specific numbers.
Cabins near the theater or other entertainment venues (commonly Emerald Deck)
The most consistently documented noise pattern across this class — reported until as late as 11pm on show nights.
Cabins directly below the pool deck
Early-morning deck-chair dragging and setup noise, reported across multiple ships in this class.
Cabins near self-service laundry facilities
A recurring complaint across several ships, though the specific cabin numbers vary ship to ship.
Obstructed-view balconies on the lower outside decks (commonly Deck 8/Emerald Deck)
Lifeboats or machinery housing block part of the view — priced lower for a reason.
Forward-facing cabins on upper decks
Reported as more exposed to wind and motion, a pattern consistent with any ship this size.
Balconies overlooked by the SeaWalk or nearby public viewing terraces
A privacy consideration specific to this class’s signature glass-floor walkway feature — worth asking about if privacy on your balcony matters to you.
The specific cabin numbers behind these patterns come from third-party cabin-selection blogs (primarily CruiseMummy and CruiseBooking) rather than Princess’s own documentation, and quality varied by ship during this research — for Regal Princess specifically, one source we found showed signs of possibly AI-generated pseudo-specific detail, so we deliberately did not carry ship-specific cabin numbers over for that ship. Treat all cabin numbers on the individual ship pages as plausible and worth checking against the current deck plan, not as independently confirmed.
What does the next dollar actually buy?
Private outdoor space — the single most-felt upgrade on any of these six ships for most travelers.
A modest but real size step — price the gap directly rather than assuming it’s automatically worth it.
A genuine sitting-area upgrade, and — if it’s the M1 Reserve Collection grade specifically — the most accessible route into Reserve Collection perks without full suite pricing.
Reserve Collection perks, priority dining and access to the private Concierge Lounge — but still not a dedicated suite-only restaurant.
The single biggest jump on this class — roughly 1,800+ sq. ft. and two bedrooms, versus 470–800 sq. ft. for the standard suite grades. Only exists on three of the six ships, and only 2 per ship.
Match the strategy to the traveler
Solo traveler
Princess does not sell a discounted solo-occupancy category on this class — budget a standard category at the single-supplement rate, the same as most mainstream lines.
Couple
Start with a standard Balcony cabin. Price Deluxe Balcony directly against it before assuming the size step is worth the fare gap.
Family
Price a Mini-Suite before assuming you need a full suite — the sitting-area upgrade is the same whether or not it carries the Reserve Collection (M1) designation.
Light sleeper
Avoid cabins near the theater or other entertainment venues, cabins directly below the pool deck, and cabins near self-service laundry facilities.
Suite-first traveler
Decide which generation first, not which suite grade — only Sky, Enchanted and Discovery Princess offer the Sky Suite; the original trio tops out at Premium Suite.
View-first traveler
On the enlarged trio, standard Oceanview is a very small inventory (6 cabins per ship) — price it against a Balcony cabin rather than assuming it’s available.
Turn the cabin premium into a daily number
Use the Seabound Cruise Value Calculator alongside this guide: the cabin framework above gives you the facts, the price gap tells you whether the next category up is worth buying.

Each ship page carries its own confirmed stateroom count, accessible-cabin figure, location-specific research and — where the six genuinely differ — the suite-grade detail, so this master page never has to fake one dataset that fits all six ships identically.
Royal Princess
First of the class — 1,780 staterooms, Owner’s/Penthouse/Premium suites.
Regal Princess
1,780 staterooms per Princess’s current ship page — not the stale 1,337 figure an older fact sheet still shows.
Majestic Princess
The most different of the original trio in public spaces — same core 1,780-stateroom cabin structure.
Sky Princess
First to offer the Sky Suite — 1,830 staterooms, two bedrooms in the top category, plus a confirmed Window Suite grade.
Enchanted Princess
Pandemic-delayed sister to Sky Princess — same 1,830-stateroom structure, plus a named Window Suite grade.
Discovery Princess
Newest of the six, and the most wheelchair-accessible by cabin count — 40 accessible staterooms.
Royal Class cabin questions
What is the best cabin on a Royal-class ship?
For most couples, a standard Balcony cabin is the easiest right answer on any of the six ships. Families and anyone wanting more space should price a Mini-Suite before assuming they need a full suite.
What is the difference between the two Royal Class generations?
Royal, Regal and Majestic Princess (2013–2017) run roughly 1,780 staterooms with no standalone Oceanview category and top out at Premium Suite. Sky, Enchanted and Discovery Princess (2019–2022) run roughly 1,830 staterooms, add a small 6-cabin Premium Oceanview category, and introduce the Sky Suite and Window Suite grades — including a two-bedroom, roughly 1,800+ sq. ft. Sky Suite flagship category — that the original trio doesn’t have at any price.
Is Reserve Collection on this class the same as Sanctuary Collection on Sphere Class?
No. Reserve Collection here includes a private Concierge Lounge and a Reserve Dining area inside the main dining room, but there’s no dedicated suite-only restaurant. Sanctuary Collection on Sun Princess and Star Princess includes a separate, dedicated suite-only restaurant and lounge — a real structural difference, not just a name change.
Which ships have the Sky Suite?
Only Sky Princess, Enchanted Princess and Discovery Princess — the enlarged-trio generation. Royal, Regal and Majestic Princess don’t offer it at any price. Even on the ships that have it, there are only 2 per ship.
How many staterooms does each Royal Class ship have?
Royal Princess: 1,780. Regal Princess: 1,780, per Princess’s current ship page (an older, cached Princess fact sheet for this ship states a stale 1,337 that should not be treated as current). Majestic Princess: 1,780. Sky Princess: 1,830. Enchanted Princess: 1,830, per Princess’s current fact sheet (a third-party aggregator’s recompiled figure runs closer to 1,780; we treat Princess’s own figure as authoritative). Discovery Princess: 1,830.
How many wheelchair-accessible cabins does each ship have?
This genuinely varies by ship rather than following one class-wide number: Royal Princess 36, Regal Princess 38, Majestic Princess 38, Sky Princess 38, Enchanted Princess 38, Discovery Princess 40 (the highest of the six).
What is the SeaWalk?
A glass-floored walkway cantilevered out over the side of the ship, roughly 60 feet long and, on some ships, over 100 feet above the water. It’s present on all six ships in this class, per each ship’s own current Princess fact sheet — a signature Royal Class feature, not exclusive to any one ship.
What is fact, what is Seabound analysis, and what we hedged on purpose
This guide reflects Seabound’s own research into Princess’s published stateroom data for all six ships, cross-checked against third-party cruise sources (CruiseMapper, Cruise Critic, cruisedeckplans.com and cabin-selection guides) current as of August 2026 — not a pre-audited or "locked" reference document. This is the largest class we’ve covered so far, and the six-ship scope surfaced more source conflicts than smaller classes have.
Sky Princess’s suite ladder: an earlier version of this guide credited Sky Princess with only four suite grades and equated Princess’s "44 suites with private balconies" fact-sheet figure with "44 standard suites," omitting the Window Suite (S7) grade entirely. Current Princess brochure and deck-plan material confirms Window Suite on Sky Princess, matching the grade already documented on Enchanted and Discovery Princess. Corrected here and on Sky Princess’s own page — we present the fact-sheet suite total and the separately-confirmed Window Suite as two published facts rather than inventing how they reconcile.
Regal Princess’s total stateroom count: an older, cached Princess fact sheet states 1,337; Princess’s current ship page and independent cabin-by-cabin sources agree on 1,780. We use 1,780 and flag the older figure as stale rather than presenting the two as an open, unresolved dispute — the newer, corroborated figure has clearly superseded it.
Enchanted Princess’s total stateroom count: Princess’s own fact sheet states 1,830, while a third-party aggregator’s recompiled category breakdown sums closer to 1,780. We treat Princess’s own figure as authoritative but note the gap rather than silently picking one.
Wheelchair-accessible cabin counts for Regal Princess (38 per Princess’s accessible-route page vs. 36 per two third-party sources) and Enchanted Princess (38 per Princess vs. 36 per a third-party source) — we present Princess’s own current figure as authoritative and note the minor third-party conflict.
Exact suite-grade-to-letter-code mapping (which code is Owner’s vs. Penthouse vs. Premium on each specific ship) is consistent across sources but wasn’t independently confirmed against each ship’s own Princess booking engine for every one of the six ships.
Gross tonnage figures showed minor discrepancies between Princess’s own materials and Wikipedia on several ships (for example, Sky Princess: roughly 141,000 per Princess’s rounded figure vs. 145,281 per Wikipedia) — tonnage isn’t cabin-relevant, so we didn’t chase every figure to ground, but we don’t want to overstate precision we don’t have.
Specific noisy-cabin numbers on the location section trace to third-party travel-tip sites, quality of which varied by ship — we deliberately did not carry over ship-specific cabin numbers for Regal Princess after one source we checked showed signs of possibly AI-generated pseudo-specific detail.
The named-tier category structure, the generational split in stateroom counts and categories, Reserve Collection’s role fleet-wide (except on Sphere Class), the private Concierge Lounge for suite guests, and the SeaWalk’s presence on all six ships are each confirmed on Princess’s own current published materials.
The core stateroom totals for Royal, Majestic, Sky and Discovery Princess, the Sky Suite’s introduction with Sky Princess, and the general location-risk pattern (entertainment venues, pool deck, laundry, obstructed lower decks) are each corroborated by more than one independent source.
Which category is the better buy for a given traveler type, how the two ship generations compare, and what each rung of the upgrade ladder is actually purchasing.
This master page doesn’t pretend one dataset fits all six ships identically, especially on suite structure and accessible-cabin counts, where they genuinely diverge. Confirmed cabin numbers and ship-specific detail belong on the six ship pages, which this guide links to throughout.
