See, in Florida and Japan and Singapore, especially Florida and Singapore, they're moving away from the soundstage concepts and making it more fantasy/realistic atmosphere now. That's what I've noticed Jon. Before, Florida was copying our atmosphere. Now with almost all recent additions, they're going the "Disney" way, save for a few soundstages like ET.
As nice as that CAN be, i think in Hollywood it works best if it makes us feel we're in a studio.
The only slight retheme to the lower lot I'd do is based on an idea Ms B had. Every ride on the lower lot is the set of a different film, so in front of each ride, or close to it, I'd have movie props, walk around "directors" "casting" for the ride/movie, etc, and maybe some "soundstage" rigs and lights, etc. To not feel as barren. I'd rename the lower lot "Production Central"
