Okay, to balance out the bummer-factor in my other question, I also wonder what everybody thinks is the best addition or change to the park since '88. My pick?
Indiana Jones Adventure. It's simply the best imagineered ride during that period in my opinion. Complete commitment to the idea and the story, no shortcuts or 'cheap route' taken in planning and building it. A real ride ride.
(Although it's not in DL park, DCA's upcoming renovation fits in here as well. Sounds as though what they're going to do will improve it remarkably)
