I really think HS is the park in need of the most help:
-First thing is first, take down the hat.
-I really think HS has sort of lost its way, does anyone in management know what the park is trying to be? A working studio? Not any more. A behind the scenes how movies work? Not so much. I really think they got it right with Sunset Blvd. That sort of 1920s Hollywood that never was and always will be. I would extend that theme tot he whole park-save for Pixar Place. The theme I would apply to the park would be one of the Hollywood Dream. The guests are aspiring actors who have traveled to try to have their big break. Each attraction would be a sort of audition. Tower of Terror for horror, RRC for music videos, Indy for adventure, Star Tours for sci-fi, and Muppets for comedy. Pixar Place for voice acting. That sort of thing.
-The park would have two themes, the Sunset Blvd. and then Pixar PLace
-I would take out the Backlot Tour and expand Pixar Place that way. Have rides based on the Pixar Films.
-Remove the HISTK play ground. Find something else to go there.
-I would also look at expanding the actual ground of the park. Whether it be in the back or off to the side where the parking lot currently is, the park needs more space and a better flow/layout.
-Lastly, I don't know if it would work due to the height of the Chinese Theatre, but at the back of the park I would build a make shift mountain with the Hollywood sign to act as a backdrop for the entire park. Again, don't know if this would work due to the fact that you would want that Hollywood sign to be 199 ft so no light has to be on top.
The park needs rides and lots of them to keep people in the park more.
