This hotel, the world's first underwater luxury resort, brings new meaning to the "ocean-view room." Situated 66 feet below the surface of the Persian Gulf, Hydropolis will feature 220 guest suites. Reinforced by concrete and steel, its Plexiglas walls and bubble-shaped dome ceilings offer sights of fish and other sea creatures. It's scheduled to open in late 2007.
