What are breakout cities? Cities that seemed to pop up in news stories with uncommon frequency, that have developed a cachet, that appear on the itinerary of early adopters. For your consideration here are four outstanding, very different candidates for this honor. Which whets your travel appetite?

Dubai City, U.A.E.
Nothing helps build a city quicker than petrodollars and a monarchy devoted to world-class projects. Dubai has all of that and more. The city that calls itself the "City Built For Tourism" is known as the home of the world's largest free-standing hotel, the Burj Al Arab. This ultra-ultra-luxury, 1,000-ft. tall hotel with a profile evoking billowing sails has quickly become the symbol of Dubai.

Under the vision of the ruler Mohammed bin Rashid Al Maktoum, Dubai has used its free-trade zone status to also develop into a world center for business. Having the world's largest manmade harbor and an airline that serves as a hub for the Persian Gulf region (with a new one under construction) helps, too. Dubai's acceptance of other culture's mores has helped turn it into a popular tourism destination, as well.
