Luxury and Dubai go hand in hand. With a seven-star property, the world’s tallest tower, manmade islands, underwater hotels and buildings that spin like a Weeble with an inner-ear infection, the city of Dubai is bar none the best at making headlines. It has built an entire tourist industry out of people’s curiosity. If you find yourself with 24 hours in the city, you’ll have no shortage of things to do. This United Arab Emirates destination is on every billionaires list.
