Spring & autumn
Mediterranean
Longer, port-rich Western and Eastern Mediterranean sailings from Italy and Spain, including smaller Greek and Adriatic ports the larger ships skip.

Celebrity Cruises · Millennium Class · Maiden voyage 2002
The newest of the four sisters — and the easiest ship in the fleet to love.
Constellation carries 2,184 guests across 11 guest decks, which is roughly half what the Edge Series carries and precisely the point. She was last revitalised in April 2024, so the staterooms, suites and public rooms are current even though the hull is 2002. What you get is the full Celebrity experience — The Retreat, Luminae, Blu, Tuscan Grille, a glass-roofed Solarium — on a ship you can learn in an afternoon, that berths in smaller Mediterranean and Northern European ports the big ships can't reach.

Onboard
A high-level look. We'll go deeper on any of these — including the shows worth pre-booking — when we speak.
Suite guests get Luminae, the Retreat Lounge on deck 4 and butler service — the same headline suite tier as the newest ships, on a ship carrying half the guests. It is the best-value route into Celebrity's top tier.
New bedding and bathrooms, restyled public rooms and a reworked pool deck. She does not feel like a 2002 ship inside — but she still handles like a smaller, steadier one.
San Marco, the two-deck main restaurant with the aft windows, plus Tuscan Grille on deck 11, Sushi on Five and Le Petit Chef at Qsine. Getting the table and time you actually want is genuinely easy here.
Adults-only, glass-roofed, with a pool and hot tub. It is why she works as well on a Norwegian fjord morning as on a Mediterranean afternoon.
Most UK Constellation fares bundle drinks, Wi-Fi and tips. We'll tell you honestly whether the standard package covers what you'll actually drink before you pay to upgrade.
At 90,940 GT she goes alongside in places the Edge Series has to tender or skip entirely. If the holiday is really about where you're going, that matters more than a waterslide.
Cabins & where to book
Constellation is 58% veranda rather than the 80%-plus of the newer ships, so the balcony categories go earlier and the good ocean-view cabins are worth taking seriously. The Sunset Verandas at the stern are the quiet prize of this class — nine of them, with a 242 sq ft terrace on the Sunset Suites above.
We'll steer you clear of the obstructed views, the cabins under the pool deck and the noisy connecting doors — and towards the ones that quietly go for the same money.
Best value
Concierge Class, mid-ship decks 8–9
Steady in a swell, short walks to everything, priority embarkation and a few sensible extras for a modest step up from a standard veranda.
Quiet pick
Sunset Veranda or Sunset Suite, aft
Only 21 of them on the whole ship, with wake views and deep terraces. On a Mediterranean or fjords sailing these go first — ask early.
Worth the upgrade
Sky Suite in The Retreat
Luminae, the Retreat Lounge and a butler on a 2,184-guest ship. On a 10- or 14-night voyage the maths works better than most people expect.
Approach with care
Deck 10 forward and under the pool deck
You'll hear deck chairs early on sea days. We'll steer you a floor or two down for much the same money.
Where she sails
A general picture of her deployment. Exact dates, ports and pricing shift — we'll confirm live availability for your window.
Spring & autumn
Longer, port-rich Western and Eastern Mediterranean sailings from Italy and Spain, including smaller Greek and Adriatic ports the larger ships skip.
Summer
Norwegian fjords, the Baltic and the British Isles, where the glass-roofed Solarium earns its keep on a cool scenic morning.
Autumn & spring
Slow crossings between Europe and the Caribbean — proper sea days on a ship built for them, and often the best value fare of her year.
