2. Poseidon Undersea Resort
Conceived and developed by U.S. submarines, Inc. Poseidon is a proposed chain of five underwater resort that first gained media attention in 2008. While there has been a lot of hype over these underwater habitats, construction keeps getting postponed for what we assume is due to engineering & architectural difficulties. The plans include a 22 room building with a library, SPA, and 1200 square foot suite. Breaking ground is still anticipated & people can be added to a mailing list for advance reservations on the company website.
