I think EPCOT's Mission to Space belongs in Tomorrowland. It is a great attraction. DL's Tomorrowland has been so neglected. The DL version of Mission to Space can of course be slightly different (and make it better). Tear down Innoventions and the Pizza Port and build it there. I think the Nemo version of Submarines will be great...I also would like Ariel, the Little Mermaid and her friends there as well so it will not all be Pixar-themed. It also would be great if the PeopleMover came back as well as per Al's updates.
What would you add to make Tomorrowland better?
