What I would actually book
My default here is a standard Veranda cabin. But I want to be upfront about something specific to this ship: the published cabin data is genuinely inconsistent, not just imprecise — so I’d treat any specific stateroom-count claim you read elsewhere, including some of mine below, with the same caution I’m applying on this page.
Veranda
296–309 cabins depending on which tracker you trust.
AquaClass
107 cabins — a 2012-and-later retrofit, not original to this ship.
Sky Suite
32 cabins.
~1,079 total
The figure I trust more — cruisedeckplans.com contradicts itself, separately stating 1,109 on the same page.
26 total
Corroborated by two independent sources — CruiseMapper and Special Needs at Sea.
Cabins 9086/9088 (AquaClass) and Sky Suite 6102
Single-source location quirks — I go into these below.
Four questions, then a starting point
You don’t need to memorize Millennium’s whole category ladder. Answer these and I’ll tell you where I’d start — keeping in mind this is an older ship with real data-quality caveats attached to more than one of these categories.
What would actually improve your room?
Four questions. Then I narrow the field instead of leaving you to compare ten categories at once.
The category ladder, bottom to top — with real data-quality caveats
Millennium runs Interior, Ocean View, Veranda (incl. Family Veranda), Concierge Class, AquaClass, and four Retreat suite tiers. I want to be direct about this: this ship’s own cabin-count data is the least internally consistent of any Celebrity ship I’ve researched for this project.
| Family | Category | Notes |
|---|---|---|
| Interior | Interior | 229 (cruisedeckplans.com) vs. 212 (CruiseMapper) |
| Oceanview | Ocean View | 244 cabins — both sources agree |
| Veranda | Veranda | 309 (cruisedeckplans.com) vs. 296 (CruiseMapper) |
| Family cabin | Family Veranda | 12 cabins |
| Concierge Class | Concierge Class | 265 (cruisedeckplans.com) vs. 158 (CruiseMapper) — a wide gap I can’t close |
| AquaClass | AquaClass | 107 cabins — both sources agree; a 2012-and-later retrofit |
| 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 states “1,109” in one summary line and “1,079 staterooms total” elsewhere on the same page — and its own per-category table sums to 1,216, matching neither figure. CruiseMapper independently states 1,079. I’m using 1,079 as the better-corroborated figure, but I want to flag this prominently rather than quietly pick a number and move on: this ship’s published cabin-count data is genuinely less reliable than on any other Celebrity ship I’ve looked at.
The entry-level tiers, with real source disagreement
Interior and Veranda counts disagree between the two main trackers by roughly 13–17 cabins each — not huge, but I’m not going to smooth it over. Ocean View (244 cabins) is the one figure both sources agree on exactly, so if you want a number you can actually rely on, that’s it.
Which perk tier is actually right for you
AquaClass (107 cabins) was added to Millennium via a 2012 refit that converted existing balcony cabins — this category didn’t exist on the ship as originally built in 2000, unlike on newer Solstice and Edge-class ships where it’s original equipment. Concierge Class shows the widest count disagreement of any category on this ship — 265 (cruisedeckplans.com) vs. 158 (CruiseMapper), a gap I couldn’t resolve. Below is how I’d actually think through the choice between the two.
Concierge Class
- Priority embarkation
- A pillow menu
- A handful of dining perks on top of a standard veranda cabin
- The easy upgrade if a balcony room is already your plan
AquaClass
- Spa-inspired cabin décor
- Access to Blu, the AquaClass-exclusive restaurant
- A wellness-forward experience built around the spa
- On this ship specifically, a retrofit — not part of the original 2000 layout
Expanded, not newly built
The Retreat existed on Millennium before 2019 — Luminae, the suite-exclusive restaurant, predates the “Celebrity Revolution” refit. What the January–February 2019 refit actually added was a redesigned Retreat Lounge (converted from the former Michael’s Club) and a new dedicated Retreat Sundeck at the front of the ship, with cabanas, a heated jacuzzi, and a private bar. Suite tiers here: Sky Suite, Celebrity Suite, Royal Suite, Penthouse Suite.
Sky Suite
This is where I’d start — the entry point into Retreat access, now with a dedicated Sundeck since 2019.
Royal Suite or Celebrity Suite
The top of this ship’s ladder — 8 cabins each, so book early if either is the goal.
No source describes a new Retreat restaurant being introduced in 2019 specifically — Luminae already existed on this ship pre-refit, which differs from later-class ships where Luminae itself was newly built in.
One of the better-corroborated figures on this ship
26 accessible cabins, corroborated independently by CruiseMapper and Special Needs at Sea (an accessibility-focused travel agency site) — two independent sources agreeing, which is honestly a rare point of consistency on this particular ship.
Confirm the exact accessible cabin number, category and door width directly with Celebrity or a travel advisor well ahead of your sailing.
Standard Millennium Class lineup — no confirmed ship-exclusive venue
Metropolitan is the main dining room. Luminae (suite-exclusive), Blu (AquaClass-exclusive), Tuscan Grille, Qsine (with Le Petit Chef), Sushi on Five, Café al Bacio, Mast Grill, Spa Café and Cellar Masters round out the offering, with Chef’s Table by Daniel Boulud highlighted on Celebrity’s own page for this ship.
Every named venue on this ship — Qsine, Sushi on Five, Tuscan Grille, Blu, Luminae — also exists across sister ships Infinity, Summit and Constellation. I found no source claiming exclusivity for any venue on this ship, so I’m not asserting one either.
What’s corroborated, and what’s one site’s word for it
The specific cabin numbers below trace to one source only; the general categorical advice is corroborated by a second, independent guide. I’d rather be precise about which is which than present it all with the same confidence.
Elevators, pool decks, lifeboats, far forward.
Pick a category above and I’ll tell you what I know — and how confident I actually am in it.
They trace to a single deck-plan specialist site and weren’t cross-checked against a second source with matching numbers in this research pass.
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 — AquaClass here is a retrofit, not original equipment.
Full Retreat access, including a dedicated Sundeck added in 2019.
The top of this ship’s ladder — 8 cabins each.
Make the upgrade prove itself
Use the Celebrity Add-On Value Evaluator alongside this guide — the cabin library above gives you the facts, and the evaluator tells you whether the price gap between two categories is actually worth paying.

Celebrity Millennium cabin questions
What is the best cabin on Celebrity Millennium?
A standard Veranda cabin is my default. AquaClass is worth pricing if wellness amenities and Blu dining access matter to you — just know it was retrofitted onto this ship via balcony conversions, not part of the original 2000 design.
Does Celebrity Millennium have AquaClass?
Yes — 107 cabins, added via a 2012 refit that converted existing balcony cabins, then expanded further in the 2019 “Celebrity Revolution” refit. It wasn’t part of the ship’s original design.
How many staterooms does Celebrity Millennium have?
Approximately 1,079 — the figure I trust more, since cruisedeckplans.com actually contradicts itself on this specific ship, stating both 1,079 and 1,109 on the same page, with its own category table matching neither.
What changed on Celebrity Millennium’s 2019 refit?
A 35-day “Celebrity Revolution” refit added 30 new cabins (13 AquaClass, 7 Ocean View, 10 Inside), a redesigned Retreat Lounge, and a new dedicated Retreat Sundeck at the ship’s front.
How many wheelchair-accessible cabins does Celebrity Millennium have?
26, corroborated by two independent sources — CruiseMapper and Special Needs at Sea.
Where can I find the official Celebrity Millennium deck plan?
Celebrity publishes the current deck plan for this ship at celebritycruises.com/cruise-ships/celebrity-millennium/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 had the least internally consistent published cabin data of any Celebrity ship in this research project, and I’ve tried to flag that prominently rather than bury it.
Total stateroom count: cruisedeckplans.com is internally inconsistent (1,079 vs. 1,109 on the same page, with its own category table summing to neither) — I’m using CruiseMapper’s corroborating 1,079 figure.
Concierge Class count: 265 (cruisedeckplans.com) vs. 158 (CruiseMapper) — a very wide gap I couldn’t close.
Interior and Veranda counts each show a 13–17 cabin gap between the two main trackers.
A November 2024 drydock is listed by cruisedeckplans.com as the “last drydock,” but no independent source corroborates this — I’m flagging it as unconfirmed rather than asserting it.
Cabin-number-specific location quirks trace to a single deck-plan specialist site, not independently cross-checked.
The 2019 refit’s scope — new cabins, Retreat Lounge redesign, dedicated Sundeck — is corroborated by Wikipedia and multiple travel-press sources.
The 26-accessible-cabin figure and the Ocean View (244)/AquaClass (107) counts are each corroborated by two or more independent sources.
Why this ship’s cabin-count data deserves more skepticism than most, and what each rung of the upgrade ladder is actually purchasing, are my own conclusions from the research above — not numbers I found written down somewhere.
