Around the world, there are many tourists attractions which render overseas cities. For example, Huis Ten Bosch is a theme park recreating towns in netherlands. Venetian in Macau and Las Vegas is casino recreating Venice. But, I've never heard tourists attractions recreating multi cities around the world.(Except for EXPO or museum displaying miniatures of the world's buildings)
So, Dubai's megaresort will allure tourists for a long time.
