While this may get me labeled as a Disney 'shipper, I don't really think any space is wasted. I don't like the way the Back Lot Tour is now (I call it the Basically Lame Tour) but I recently read an article about how much history and props are stored back there. Plus, the awesome AFI Store that most people just rush through. It's the Hollywood Studios and the emphasis should be on film and not just rides, rides, rides. I nice slow thing is good every once in a while. That being said, I liked it much better than Lights, Motors, Action! But that's one of my husband's favorites. It's really to each his own.
Would I like to see more countries at Epcot? Sure! But I would also like to continue seeing the natural beauty that is World Showcase. Would I like to see Camp Minnie-Mickey gone (we have no kids at home)? Sure! But there is something nice about that area.
I dunno, I guess I just try and see the good stuff.
