This is one of those real things that at first seems too amazing to believe until you do a little research to confirm that it is in fact a real Tennis Court - the highest in the world. The Burj-al-Arab is one of the world's most luxurious and spectacular hotels. Rooms are $2000 per night unless you opt for a top suite where you can expect to pay some $28,000 per night.
The helipad at the top of the hotel was turned into a tennis court for Andre Agassi and Roger Federer when they were visiting for the Dubai Open. Amazing.
