About Celebrity Infinity
Celebrity Infinity, from 2001, is the second Millennium-class ship and originally opened with a specialty restaurant decorated with fittings from the famous liner SS United States. Today it carries more recent Celebrity touches, including Tuscan Grille and Café al Bacio, while keeping the class’s gracious, slightly classic interiors. Its itineraries have taken it from the Caribbean to Europe and around South America. With fewer guests than Celebrity’s newer ships, it offers a relaxed pace that suits longer, port-rich itineraries, though it lacks the Lawn Club and the Edge-class showpieces.
Best for: Experienced cruisers who want premium service on a mid-size ship for longer itineraries.
