Celebrity Constellation

Celebrity Constellation is the fourth and last of the Millennium-class ships, launched at Saint-Nazaire in October 2001 and in service since 2002. She sailed her first five years simply as Constellation; the “Celebrity” prefix was added in 2007 to bring her into line with her three sisters. At twenty-four she is the oldest ship Celebrity still operates in any volume, and the honest thing to say about her is that she has had less money spent on her than any of them.

The turbines

Almost every large cruise ship built in the last forty years burns diesel. The Millennium class does not. Constellation has a COGES plant: two General Electric gas turbines and a steam turbine recovering their exhaust heat, feeding about 60 megawatts to the electrical system, with two 19 MW Rolls-Royce/Alstom Mermaid azimuth pods doing the pushing.

The reason anyone did this was noise. A gas turbine sits high in the funnel casing rather than deep in the hull, and the vibration that most ships transmit up through the aft cabins is largely absent here. It also makes her fast: 24 knots service speed, which is quicker than most ships half her age and is why she can hold a sixteen-night itinerary together without cutting ports.

The catch is that gas turbines drink. Fuel prices moved against the design almost immediately after delivery, and in 2007 Celebrity fitted an additional diesel engine specifically as a fuel-saving measure; the turbines now get switched off when the schedule allows it. It is a good engineering story and a bad commercial one, and it is part of why the class has never justified the investment the newer ships get.

The refit that did not happen

In 2018 Celebrity announced Celebrity Revolution, a $500 million program to take every Millennium- and Solstice-class ship apart and rebuild the interiors to match the then-new Edge. Millennium, Summit and Equinox went through it in 2019 and Silhouette in early 2020. Constellation was booked for May 2020.

She never went. The 2020 slot was canceled outright, a replacement refit promised for mid-2021 was also dropped, and the program was quietly wound down. What she eventually received was three weeks at Chantier Naval de Marseille in April 2024: the main dining room refloored, re-upholstered and re-clad, the Ocean View Cafe rebuilt, the hot tubs replaced, the pool deck tidied and the Retreat spaces refreshed. That is a competent refresh of the surfaces people touch most. It is not the bow-to-stern job her sisters got, and her interiors below that layer date from her last comprehensive overhaul in 2013.

What she does have from that 2013 round is the useful part of the Solstice-class playbook: AquaClass cabins with Blu as their dining room, Luminae and a Retreat lounge for suites, Tuscan Grille, Le Petit Chef, and a Chef’s Table menu built with Daniel Boulud. Starlink went in fleet-wide, so the internet works.

Where she actually sails

Two winters, effectively. Most of her Caribbean program runs from Tampa, which Celebrity returned to in 2020 after thirteen years away, with a second block of southern Caribbean weeks out of San Juan, the shorter, port-dense kind that only work from a base that far southeast. In between she crosses the Atlantic and spends a European season working out of Civitavecchia for Rome and out of Ravenna for the Adriatic and the eastern Mediterranean, on runs from a week up to sixteen nights.

Her size is the point of that deployment. At 965 feet and ninety thousand tons she gets into Adriatic and Caribbean berths that the Edge-class ships cannot use, and she carries a fifth as many people as the largest ships calling at the same quay.

Who she suits

People who want the itinerary rather than the ship, and who would rather be one of 2,184 than one of 5,000. The Adriatic and southern Caribbean routes she runs are genuinely better than the standard four-port loops, and she is small enough to make them work.

She does not suit anyone who wants a new ship. The public rooms are handsome and dated, there is no Magic Carpet and no waterslide, the theater is a conventional proscenium house, and the layout is a 2002 layout. Families with teenagers will find very little aimed at them. If the phrase “recently modernized” is what sold you, book a sister; Millennium, Summit or Equinox actually got the work.
