For the ultimate adventure vacation, spend a day or two at this resort. Formerly an underwater research laboratory, its one unit consists of a single bedroom and a galley, room for up to six people. Sitting atop pillars in the ocean floor, guests swim under the structure and through a four-foot-by-six-foot "moon pool." Room service delivers breakfast, lunch, and daily newspapers in waterproof containers. It is advised to book reservations early.
