It's too bad that Marvel characters can't be used at WDW. The first thing I would've done was give Stitch the boot and drastically retheme the building, transforming it into "The Weapon X Experience ." The attraction would follow the story of Bill Stryker's ongoing project of enhancing mutant superpowers for "weapons of tomorrow." Today's subject, Nightcrawler. A mutant who specializes in teleportation, though things go wrong when Nightcrawler decides that it's time to make his grandest escape. Guests will experience the ultimate showdown between mutant and humans. This attraction will complement the beloved ExtraTERRORestrial Alien Encounter, as it will follow the same format, just changing the story and characters... But like I said, it's too bad WDW can't touch those characters. (I READ THE CONTRACT!)
I think Buzz needed to go when TSM opened back in 2008, even the Laugh Floor should go. Combine the two buildings together (maybe build in some additional floors) and make a Tron attraction out of it. Also, I think the Tomorrowland speedway has ran it's course and with Carsland apparently coming to DHS, I say retire the track and use the space for a well deserved attraction. Space Mountain needs a major refurbishment (new track, audio, story) and I'm staying hopeful that the upcoming Space Mountain movie adaption will do well so it will increase our chances of this happening. They've done it with Pirates, I don't see why they can't do it with Space Mountain.
All of this has been brought to you courtesy of... wishful thinking!
