Okay, here we go. This park is supposed to be centered around movies, right? And there's really not that much to do with movies! So, a few ideas:
There needs to be an attraction deal where people go through and see everything that goes on behind the scenes on movie sets: make-up, cameras, set design, lighting... And in the beginning, a group of maybe five or six people should be selected to undergo the actual behind the scenes stuff. Three people should be picked to have make-up and costuming done, and given a short little skit to memorize. Another small group should be tutored in cameras. At the end of the tour, the original group would be able to watch the three actors, which would be recorded by the people taught to operate the cameras. When it's all over, the people invovled in the skit would be able to buy a DVD of their performance.
There should be a fully-operational Broadway section. Mini-theatres, stores offering Broadway merchandise, little cafes with a theme around famous stage actors... And in one of these theatres...
It should run a condensed version of a Disney musical that's been on Broadway. While there would be actual actors there, guests would be able to sign up, for an additional fee, to learn parts in the show and perform amidst the real actors. These shows would actually be filmed and have their own TV station on the TVs in the hotel rooms.
