The 2,850-passenger Celebrity Equinox is the second ship in Celebrity Cruises' stunningly gorgeous Solstice class. One of two ships in this class (the other is Silhouette) that have undergone the cruise line’s “Revolution,” which brightened décor and added Edge-Series amenities, Equinox elicits oohs and aahs for its stylish design. Knockout spots include the South Beach-style pool area, done up with cushy loungers and water fountains, as well as the stylish Grand Foyer featuring onyx staircases.
