Guess where President Bush stayed last weekend on his Middle East trip? The oil-rich outpost of the United Arab Emirates boasts the most extravagant luxury hotels in the world, like the seven-star Burj Al Arab where aquarium walls full of tropical fish line the escalators, and the world's largest fleet of Rolls-Royces is available for guests.

President Bush, arriving in Abu Dhabi over the weekend, stayed in one of the basketball-court-size "Ruler's Suites" at the Emirates Palace, which bills itself as the world's costliest hotel. At $3 billion, with 300 rooms, that comes out to $10 million a room.

In this spare-no-expenses kingdom, the opulent Emirates Palace stands out because of its brand new Anantara Spa. You'll find an enormous private treatment complex, Vichy shower suite, hammam with heated marble beds, and intricate architectural details: Moorish tile floors beneath a glowing domed ceiling. Return to your room, sauntering down the hallways shimmering with gold mosaics, and enjoy private butler service and Hermes bath amenities.

P.S. We hear the hotel's best suite is the 1,185-square-foot Khaleej Suite, overlooking the Persian Gulf.
