The above picture is from the Poseidon Undersea Resort located in Fiji. Yes that's right, it's an underwater hotel. It is located on "Poseidon Mystery Island" and if you can afford the $15,000US per person then I highly suggest you look into this. Some highlights of vacationing with Poseidon Undersea Resort are, once you land at the airport in Fiji you are picked up by a pilot and flown in a private plane to the Mystery Island, four nights in a luxury beach/over-water villa, two nights in a luxury under-sea suite, walks on the Lagoon floor with their Sea-Trek system, and many other very cool things. If you have $15,000 kicking around then you should definitely check out the Poseidon Resort.
