GTS Millennium is the flagship of the Millennium-class cruise ships, operated by Celebrity Cruises line. Her sister ships are Constellation, Infinity, and Summit.

Construction and Description

Millennium was built at Chantiers de l'Atlantique in St. Nazaire, France. When launched in 2000, she was the world's first ship to use a turbo-electric COGAS power plant. Combined gas and steam (COGAS) is the name given to marine compound powerplants comprising gas and steam turbines, the latter being driven by steam generated using the heat from the exhaust of the gas turbines. In this way, some of the otherwise lost energy can be reclaimed and the specific fuel consumption of the plant can be decreased.

Millennium has a restaurant that contains wooden panels originally used in the RMS Olympic (sister ship to the ill-fated RMS Titanic and HMHS Britannic), removed and preserved when that ship was sold for scrap in 1935.

Sources of food include a two level main dining room, called "Metropolitan", and a buffet that serves breakfast, lunch, and dinner on deck 10.

Drydock

After the ship's voyage from Miami to Roatan, Honduras, to Cozumel, Mexico, and back to Miami (April 16–21, 2012), the ship went to dry-dock in the Bahamas for 3-weeks to be renovated.

Depending on the season, the ship visits the following destinations: Alaska from Vancouver and Seward during the summer season, Hawaii and South Pacific Ocean in fall and Southeast Asia from Singapore and Hong Kong during the winter season.

In early 2019, the ship underwent another dry dock.
