What I would actually book
My default here is a standard Veranda cabin. If you want a suite-tier upgrade with Retreat access, go in knowing this ship’s Retreat is restaurant-and-lounge only — there’s no dedicated suite-guest sundeck here yet, and I don’t want you finding that out on embarkation day.
Veranda
276 (cruisedeckplans.com) vs. 296 (CruiseMapper) cabins.
AquaClass
107 cabins.
Sky Suite
32 cabins.
1,065 total
The best-supported of three disputed figures (1,065 / ~1,079 / 1,092) — the only one where the category breakdown sums correctly.
26 total
Corroborated by two independent sources.
No dedicated Retreat Sundeck
Confirmed directly on Celebrity’s own current site — don’t assume suite guests get a private sundeck here.
Four questions, then a starting point
You don’t need to memorize this ship’s whole category ladder. You need two or three categories that actually fit your trip, and then you need the prices. Answer these and I’ll tell you where I’d start.
What would actually improve your room?
Four questions. Then I narrow the field instead of letting the booking engine walk you upward one category at a time.
The category ladder, bottom to top
Constellation runs Interior, Ocean View, Veranda, Concierge Class, AquaClass, and five Retreat suite tiers — including a Sunset Suite (12 cabins), even though Celebrity’s own marketing page for that category reads as Infinity-exclusive.
| Family | Category | Notes |
|---|---|---|
| Interior | Interior | 218 (cruisedeckplans.com) vs. 212 (CruiseMapper) |
| Oceanview | Ocean View | 244 cabins — both sources agree |
| Veranda | Veranda | 276 (cruisedeckplans.com) vs. 296 (CruiseMapper) |
| Retreat suite | Sunset Suite | 12 cabins, per cruisedeckplans.com — confirmed present on Constellation’s own current Retreat page too (matching Infinity’s description), though Celebrity’s dedicated Sunset Suite marketing page reads as Infinity-exclusive — an unresolved self-contradiction |
| Concierge Class | Concierge Class | 158 cabins — both sources agree |
| AquaClass | AquaClass | 107 cabins — both sources agree |
| Retreat suite | Sky Suite | 32 cabins |
| Retreat suite | Celebrity Suite | 8 cabins |
| Retreat suite | Royal Suite | 8 cabins |
| Retreat suite | Penthouse Suite | 2 cabins |
cruisedeckplans.com gives 1,065, and its own category breakdown (including its published 12-cabin Sunset Suite figure) sums exactly to this: 218+244+276+158+107+32+8+8+2+12=1,065. CruiseMapper’s ship-review page separately gives ~1,079 via its cabins sub-page, and Gangwaze gives 1,092 across "21 categories." I use 1,065 since it’s the only figure whose underlying category table actually adds up to the stated total.
The entry-level tiers, with real disagreement
Interior and Veranda counts each show a real gap between the two main trackers (6 and 20 cabins respectively) — I haven’t found a way to close either gap. Ocean View (244) is the one figure both sources agree on exactly, so that’s the number I’d lean on if you need one clean data point.
Which perk tier is actually right for you
Concierge Class (158) and AquaClass (107) are the two categories where both major trackers agree exactly — both were added to this ship in the 2013 "Solsticizing" refit, which converted 70 Concierge Class cabins to AquaClass and added 37 new AquaClass cabins. The counts aren’t the interesting question here; which perks you’d actually use is. Pick a column below.
Concierge Class
- 158 cabins — one of the most consistently confirmed figures on this ship
- Priority embarkation and the fleet-standard concierge perks layered onto a Veranda-style cabin
- A lighter step up than committing to a wellness-focused category
AquaClass
- 107 cabins — also one of the most consistently confirmed figures on this ship
- Spa-leaning cabins and complimentary access to Blu, the AquaClass-exclusive restaurant
- Added to this ship in the 2013 "Solsticizing" refit, which converted 70 Concierge Class cabins into AquaClass and added 37 new ones — this category has real history on Constellation specifically
A resolved ambiguity: full restaurant and lounge, no sundeck
Celebrity’s own current Constellation Retreat page confirms a full Luminae restaurant and a Retreat Lounge — the former Michael’s Club, renamed and refreshed in the April 2024 refit. But the same official page explicitly states the Retreat Sundeck is "currently not available on Celebrity Constellation," grouping this ship with Solstice, Eclipse, Reflection and Infinity. I found this independently corroborated by a Retreat-specialist review and by the ship’s own Deck 12 plan, which lists only Sports Deck, Sports Deck Forward, and Rooftop Terrace — no Retreat Sundeck or Bar.
Sky Suite
Full access to Luminae and the Retreat Lounge — but not a dedicated suite-guest sundeck, unlike some sister ships.
Sunset Suite
12 cabins, confirmed present on this ship’s own Retreat page — despite Celebrity’s separate marketing page for the category reading as Infinity-exclusive.
CruiseMapper’s ship-review page and Deck 12 plan both assert a "Retreat Sundeck… added at the front" during a "2020 Celebrity Revolution overhaul." I think this is templated/erroneous content reused across multiple ship pages — it’s contradicted by three more specific, ship-particular sources above, and the "2020 $70M overhaul" it references doesn’t appear in any other source (the actual 2020-planned refit was COVID-delayed and effectively superseded by the April 2024 refit — see the accuracy section).
An earlier version of my research stated the April 2024 refit converted Ultra Deluxe Verandas into Sunset Suites on this ship. A follow-up pass couldn’t find a source specifically describing that conversion for Constellation — the one detailed trade-press account of Constellation’s actual April 2024 refit covers only main-dining-room reupholstering, an Oceanview Café refresh, and pool-deck jacuzzi replacement, with no suite conversion mentioned. That Ultra-Deluxe-Veranda-to-Sunset-Suite narrative is well-documented for sister ship Infinity’s January 2024 refit instead, and cruisedeckplans.com’s own category page dates Constellation’s Sunset Suite category to April 2025, a year after the refit I’d originally attributed it to. The category is confirmed present on this ship either way — I just no longer assert exactly when or how it arrived.
Corroborated by two independent sources
26 accessible cabins, corroborated by CruiseMapper’s cabins page and Cruise Critic’s cabins editorial, spread across inside, oceanview, balcony, Concierge Class and Sky Suite categories.
Confirm the exact accessible cabin number, category and door width directly with Celebrity or a travel advisor well ahead of your sailing.
San Marco, and a real venue-history correction
San Marco is the main dining room. Blu (AquaClass-exclusive), Luminae (Retreat-exclusive), Tuscan Grille, Qsine (with Le Petit Chef), Sushi on Five, Bistro on Five, Café al Bacio and Spa Café round out the offering, with Chef’s Table by Daniel Boulud referenced on Celebrity’s own overview page.
CruiseMapper’s ship-review page claims a 2017 drydock "replaced Ocean Liners Restaurant with Tuscan Grille" — but two independent, more specific sources (cruisedeckplans.com and a dedicated cruise-line blog) both state Ocean Liners was actually replaced by Qsine in 2017, with Tuscan Grille having already been introduced back in the ship’s 2013 refit. I’m going with the two-source Qsine version as more credible.
One solidly corroborated finding, the rest generic or single-source
The clearest, ship-specific location finding I have on this page comes from Cruise Critic’s own cabin-guide editorial. Tell me what you’re actually deciding and I’ll tell you how confident I am in the answer.
Start with what’s actually confirmed: Deck 6.
With no strong preference stated, I’d anchor on the one solidly corroborated finding I have — Deck 6 as the ship’s best real estate, home to the Penthouse, Royal and Celebrity suites.
A separate "cabins to avoid" blog gives only generic categories (forward cabins for motion, near-elevator noise) with no ship-specific cabin numbers — this reads as templated content reused across many different ship pages and I wouldn’t treat it as Constellation-specific.
What does the next dollar actually buy?
A window with no balcony.
Private outdoor space, my default choice on this ship.
Priority perks or wellness extras plus Blu access — the two most consistently confirmed figures on this ship, see the comparator above.
Full access to Luminae and the Retreat Lounge — but not a dedicated sundeck.
The top of this ship’s ladder as I’d lay it out — both on Deck 6, "the best real estate on the ship" per Cruise Critic.

Celebrity Constellation cabin questions
Does Celebrity Constellation have a Retreat Sundeck?
No — confirmed directly on Celebrity’s own current site, which lists Constellation among ships lacking this feature, alongside Solstice, Eclipse, Reflection and Infinity. This ship does have a full Luminae restaurant and a Retreat Lounge, just not a dedicated suite-guest sundeck.
What changed on Celebrity Constellation’s April 2024 refit?
Michael’s Club was renamed and refreshed as the Retreat Lounge, pool-deck jacuzzis were replaced, and the main dining room and Oceanview Café were refreshed. (An earlier version of this page also attributed the ship’s Sunset Suite conversion to this refit — a follow-up pass couldn’t confirm that specific timing; see the Retreat section.)
Does Celebrity Constellation have a Sunset Suite?
Yes — 12 cabins, confirmed on this ship’s own current Retreat page — though Celebrity’s separate dedicated Sunset Suite marketing page reads as exclusive to Celebrity Infinity. That’s a genuine self-contradiction on Celebrity’s own site that I haven’t resolved; I’d treat "Infinity-exclusive" claims about this category with skepticism and confirm directly before booking.
How many staterooms does Celebrity Constellation have?
1,065 is the best-supported figure of three disputed totals (1,065 / ~1,079 / 1,092) — it’s the only one where the underlying category breakdown actually sums correctly.
Is Celebrity Constellation the newest Millennium Class ship?
Yes — entered service in 2002, the newest of the four ships in the class (Millennium 2000, Infinity and Summit both 2001).
How many wheelchair-accessible cabins does Celebrity Constellation have?
26, corroborated by two independent sources.
Where can I find the official Celebrity Constellation deck plan?
Celebrity publishes the current deck plan for this ship at celebritycruises.com/cruise-ships/celebrity-constellation/deck-plans — use it to confirm the exact cabin number, deck and any obstruction before booking.
My own research — verify specifics before you book
This page is my own research into Celebrity’s published stateroom data, cross-checked against third-party cruise sources current as of August 2026. This ship’s Retreat-Sundeck status had been ambiguous across sources before I dug into it — I resolved it in favor of "no dedicated Sundeck" based on three converging, more-specific sources against one templated-looking outlier.
Total stateroom count: 1,065 (cruisedeckplans.com, self-consistent) vs. ~1,079 (CruiseMapper cabins sub-page) vs. 1,092 (Gangwaze) — a genuine three-way disagreement; I use 1,065.
Interior count: 218 vs. 212 (6-cabin gap). Veranda count: 276 vs. 296 (20-cabin gap) — both unresolved.
A CruiseMapper claim of a completed "$70M Celebrity Revolution" refit executed April–May 2020 at Navantia Cadiz isn’t corroborated by any other source and conflicts with Wikipedia’s account that 2020 work was delayed by COVID — I treat it as unverified/likely inaccurate.
The Ocean Liners → Qsine/Tuscan Grille venue-replacement history is corrected against a conflicting CruiseMapper claim (see dining section).
When and how the Sunset Suite arrived on this ship is now unclear to me — an earlier version of my research attributed it to the April 2024 refit (Ultra Deluxe Veranda conversion), but a follow-up pass found that narrative better documented for Infinity’s January 2024 refit, and cruisedeckplans.com dates Constellation’s Sunset Suite category to April 2025. The category’s presence itself is confirmed either way.
The absence of a dedicated Retreat Sundeck, the April 2024 refit’s Retreat Lounge refresh, and the Sunset Suite’s presence on this ship (12 cabins) are each confirmed on Celebrity’s own current site. The Sunset Suite’s claimed exclusivity to Celebrity Infinity is NOT reliably confirmed — Constellation’s own Retreat page directly contradicts it.
The Concierge Class (158) and AquaClass (107) counts, and the 26-accessible-cabin figure, are each corroborated by multiple independent sources.
Resolving the prior ambiguity around this ship’s Retreat Sundeck status, and correcting a conflicting dining-venue-history claim I found in one source, are both my own conclusions from the research above.
