Emirates Palace, Abu Dhabi
The most luxurious hotel I have ever seen. No expense was spared building this place. A pattern that seems to repeat in this corner of the world. It cost USD $3.0 Billion to build and it spans 850,000m2. The largest room, The Palace Grand Suite, has 680 m2. If you can't picture that, imagine a 26m x 26m square, or half the white house (look at red square in photo below).
Standard room (60 m2) - usd $400
The Palace Grand Suite (680 m2) - usd $11,500
Better start saving...
I took a few photos but you can't really appreciate this place from the ground so I've made a Google Earth screenshot as well.
Oh ... and did I mention it's a 7 star hotel :)
