Autopia is one of those attractions that might best be relegated to Yesterland. But what to do with all that space?
A new attraction would have to preserve the Monorail track (let's not close it down again). It also must not intrude upon the Submarine show building which is largely underneath the Autopia. One thought -- this area never seemed to quite fit into either Tomorrowland or Fantasyland. With the Matterhorn being very prominent in the area, why not have the Imagineers build a coaster similar to Alpengeist at Busch Gardens Williamsburg? The themeing is perfect (with all of the trees and rockwork) and would blend nicely with the European feel that this area possesses.
What are your ideas?
