Move Roger Rabbit to Fantasyland and remove the motorboat area. The coaster can be added to Frontierland as a western themed kiddie ride.
That is the biggest waste of space and remember it was the last land added. Critter Country has Pooh and Splash Mountain with a nice snack spot and stores and the canoes and a restaurant and a nice downstairs ares for resting.
As they currently stand, I'd get rid of Tomorrowland. It's such a disaster of theme and underwhelming rides that I barely go there even though it has a lot of attractions. It's too bad because it used to be great.
Adventureland - mainly to be a contrarian, but also because Jungle Cruise and Indy take up vast amounts of real estate and I wouldn't really miss them if they were gone and that space was used for something else.
Critter Country. IT was neck and neck with Toon Town, but I love the idea of Toon Town, more than I like critter country. Pooh could and should live in Fantasyland, and Splash, as a flume ride, could fit within Frontierland if it had less of the characters in it.
