The problem with Disney is they do things on what they think will be great, versus actually asking people what they think would be great.
Any and all surveys that people can take can also be completely deconstructed to their viewpoint. So asking us what we want, or what we like, will always be interpreted into what they want and what they like.
But if this expansion is going to be done, it has to be done right, which is proper lands and a more of a hub and spoke layout hopefully.
Star Wars Land
-3 rides total, Star Tours, plus an e ticket and c ticket
-Jedi Academy
-Mos Eisly Cantina
Pixar Land
-RSR
-Monsters Inc Door Coaster
-Expanded TSMM
-Flat rides for kids
-Hollywoodland
-Include current entrance, Chinese Theater, Sunset Blvd area, Animation and Disney Jr areas
-Add more Hollywood themes and movie references maybe a museum of props and combine it with One Mans Dream
-Include a show building with rotating "mini" performances of the existing and former Broadway productions
-Build a backdrop or cut out mountain with famous "Hollywood" or Hollywoodland" sign in the area in between TOT and RRC
Just some of my ideas
