I'm extremely torn. Tomorrowland was by far my favorite land as a kid, but in retrospect I think it's always been the redheaded stepchild of Disneyland. Walt himself didn't get a clean sheet of paper on that one. Financial limitations compelled him to let it be dominated by improvised attractions (20,000 Leagues) and corporate showcases (Bathroom of The Future, anyone?). While it came into focus for a little while (say, 1967-74), it's never had the unity of conception that New Orleans Square or Main Street USA had, to name two examples.
My solution? (Work with me here)
Who's the biggest individual stockholder in Disney? Steve Jobs. I suggest we convince him to let his greatest visionaries, at Apple and Pixar, go wild. No, Tomorrowland doesn't have to become a showcase for Apple technology (although that would be an improvement on the tired Microsoft displays in Innoventions)--if anything, it would be a canvas for those insights that don't fit into the consumer product category.
It's a unique opportunity. Tomorrowland is the ONE land, in all that parks, that everyone, even rabid fans, want to see change, and big time. The future is waiting to be claimed.
