My big idea, Part 2.
1.) Shift the Tram Tour station to the Backlot area, alongside the Cafe des Cascadeurs. In its place, behind the new backdrop that going to built to mark the end of the Hollywood Boulevard, build a brand spanking new central plaza. This will mark the true heart of the park, and will be a nice, open, green space with some intricate coloured tiling on the floor (think the Parque Guel in Barcelona), winding little paths, trees and maybe a water feature or two.
2.) Leading away from this, out past the rear of the park, build another street set, but on a different theme. Perhaps a 1930s Chicago street, populated by gangsters and their molls. You could call it "Mean Street USA". The buildings on this stretch of street would not be mere facades, but would contain a few shops, and the park's first full service restaurant. (My idea is to call it "The Rabbit Hole" and fill it with subtle references to Jessica Rabbit).
The new Tram Tour station would be housed on the left hand side of this street (when you're standing with Studio 1 behind you), and would follow a different route, starting with the Reign Of Fire set, and running along behind the Chicago facades on that side of the street.
3.) Mean Street USA would culminate in a large signature building of some sort, housing a totally new and exclusive E-ticket attraction. I have no idea what this could be - something using the Test Track system would indeed be fun, or perhaps an EMV ride. Or then again, something unlike anything at any of the other Disney parks would be great. Answers on a postcard!
4.) A new version of Fantasmic would be built on the land behind Rock 'n' Roller Coaster and Moteurs... Action! This would be accessible each evening, either by a new path built between the two Backlot attractions, or via a crossing from Mean Street USA, after the last tram of the day has completed the circuit.
I've only seen the Disney/MGM version of the show, and wasn't too impressed, so I propose something a bit punchier, perhaps on a smaller scale but more dramatic. And with a storyline that spans Disney animation from "The Skeleton Dance" to "The Lion King".
