Dubailand Theme Parks

Does anyone think a huge dubailand style collection of theme parks could be built in the United States? Dubai seems cool but it is far away for Americans to travel, not to mention it's in the middle east. For those of you who don't know what Dubailand is, it's supposed to be the largest collection of themeparks in the world, with a resort that spans like 100 miles. It would be cool to have something like that here, but could it be possible?

Dubailand vs Disneyland? Dubai is undergoing a major project to build Dubailand ( a major theme park), Once Dubailand is completed it will be even bigger than Disneyland. Once it is completed would you rather go to Disneyland which is closer if you live in America, or Dubailland which is further away but will be on a larger scale.
