I was thinking the same thing. Can be named "The Universal Express". A train ride taking you through the time of Universal Orlando resort or through many movies and scenes of Universal pictures. Having 3 or 4 floors with about 8 movies in which guest can get a short "Experience" of the movie that that group votes on. Something interactive such as characters, sound effects, lights, vehicle motion, etc. Then the train would do this on each floor in the section it goes through. Then IDK if this is possible but the train could interact on the outside as well. Possible going around the park and the lagoon to show progress and future developments so people get the full experience of Universal.
They knock down the Shrek building along with Lucy and rebuild that into a building similar to transformers but maybe even 1 or two stories taller.
Use that space and if they decide to do away with Mels, that space as well to do as needed. The queue could be pictures of rides, families, past experiences, etc.
Just a thought lol
You guys have some great ideas. I decided to finally join the forum.
