Watch out Orlando, Dubai wants to be the world's biggest theme park destination

On the roster is everything from big brands like Legoland and Six Flags, to new concepts set to make a splash. Literally in the case of Pearl of Dubai, slated to be the world's largest underwater park when it's completed (the tentative date is 2020, to correspond with the Dubai World Expo). Size is a theme for many of the parks on the list. One proposed project, IMG World of Adventure, hopes to usurp Ferrari World as the world's largest indoor theme park. It will include four zones, including The Lost Valley -- a Jurassic Park-themed segment -- as well as two zones dedicated to characters from Cartoon Network and Marvel Comics, respectively, CNN reports. "We want this park to be one of the center points in the future of Dubai," explains Adam Alexander Page, the vice president of marketing for IMG Group, the developer behind the project. "As such, you don't want to build something that won't get global attention, and if that means it's big, that's what you do. There's no point in building it small." What's in a name? Many of Dubai's developers plan to rely heavily on pop culture and name recognition in bringing people to their parks. This is especially true of the planned Dubai Parks, planned in an expanse 60 kilometers (37 miles) from Dubai International Airport. A theme-park conglomerate, Dubai Parks will house a Legoland, as well as a Bollywood-themed park and the Hollywood-themed Motiongate Dubai. "Movies have become the kind of entertainment that binds people, young or old, across the globe, because they all watch the same movies," notes John Gerner, a theme park consultant and the managing director at Leisure Business Advisors. "It used to be that if you were to develop a theme park, you'd take an indigenous theme unique to the area and build on that. Now, it's almost the opposite. You take an international concept known around the world, like Marvel."
