Glitzy Dubai is the United Arab Emirates' holiday hot spot. This city of high-rises and shopping malls has transformed itself from a desert outpost to a destination du-jour, where tourists flock for sales bargains, sunshine, and family fun. Dubai is famous for sightseeing attractions such as the Burj Khalifa (the world's tallest building) and shopping malls that come complete with mammoth aquariums and indoor ski slopes.
