    Millennium Class

    Back to Celebrity Cruises
    Introduced
    2000
    Capacity
    2,170 – 2,218 (double occupancy)

    Millennium Class comprises Celebrity Millennium (2000), Infinity (2001), Summit (2001), and Constellation (2002). At roughly 91,000 GT and 2,170-2,218 double-occupancy guests, they are the smallest current Celebrity ships and materially more manageable in smaller ports than the flagship classes.

    All four ships have received the Revolution refit programme, bringing the Retreat, AquaClass, and dining venues in line with newer classes. The smaller hull size preserves benefits that the flagships cannot match — better crew-to-guest ratio, faster tendering, and access to smaller Mediterranean, Asian, and South American ports.

    Deployment is deliberately global and often unusual — South America, Asia, Bermuda, the Middle East, Grand Voyages. For guests prioritising ports and itineraries over onboard theatrics, a Millennium-class ship is often the correct answer within the Celebrity fleet.
