5 spots for undersea luxury

Poseidon Resort is the brainchild of L. Bruce Jones, the president of U.S. Submarines, who is best known for building $80 million custom submarines -- so he knows a thing or two about underwater living.

Scheduled to open in 2009, Poseidon will have 24 underwater suites, all decked out with flat screen televisions, marble bathrooms and a sitting room with a library. About 70 percent of each room will be glass. There will also be 48 beach bungalows in case you feel like being closer to sea level.

Apart from relaxing in their suites, guests can spend their days exploring the sea in a personal, 1,000 foot Triton submarine, scuba diving or indulging in spa treatments. There will also be an underwater library, a wedding chapel and multiple restaurants. The cost? $15,000 per person per week, based on double occupancy.
