Check this out! This is an underwater hotel scheduled to open in 2010 in Istanbul, Turkey. Apparently, Istanbul will be the place to be as the opening will be around the same time it will be nominated as the Culture Capital of Europe and become a top player in the tourism industry globally. It is said to be at a 7-star rating!
Sounds like it will definitely be something of an experience. Dubai also has one in the works named Hydropolis, as well as the Poseidon Underwater Resort in Fiji. Hydropolis seems to be a possible setting for an old James Bond flick to me haha. I'll definitely be looking into booking a stay there when I can afford it haha. You can bet rates will be a little steep...
And for Fiji:
Sounds like a good time and looks great to me. Who's on board?
