The world's seas are the inspiration for this megaliner. Shades of turquoise, green, gold and blue are repeated in public rooms throughout the ship, evoking the colors of the ocean. Handmade glass-tile mosaics of mermaids and other mythological sea creatures swirl about the walls of the soaring nine-story main atrium, while overhead, a sky dome of illuminated Tiffany-like glass creates a magical "window under the sea." The three-story Caribbean Lounge sets the stage for Vegas-style revues, and passengers can join sing-alongs at the Irish Sea bar or go dancing in Club Arctic. Outdoor amenities include four pools, whirlpools, a 214-foot spiral waterslide, shaded bars, entertainment stages and plenty of open deck space. A pair of two-level dining rooms, Atlantic and Pacific, are complemented by a two-deck poolside restaurant and 24-hour pizzeria. The Coral Sea Cafe, which has the atmosphere of a sophisticated beach cabana, serves coffee, liqueurs and sweets.
