Undersea resort

I don't know about this.

Our resort will be the world's first permanent one-atmosphere sea floor structure and the world's first true undersea resort. Guests will enjoy 5 star luxury accommodation, all with stunning views of the underwater world. . .

We estimate that the room rate for a standard 550 square foot undersea suite will e $1500 per night. The Poseidon Undersea Resort will be the only place where you can spend a night underwater on the sea floor with a spectacular view. The "once in a lifetime" experience will be worth every penny.
