I love DHS, it's always the first park I visit but it's obvious it needs something new, move the hat, dont get rid of it though cos I actually like it, then upgrade the GMR and have the theatre as the icon of the park. Use the George Lucas connections to full potential, star wars is over 30 years old but is still as popular as ever, can't think of any other franchise that has endured that long yet it only has 1 ride and a cool shop. Same goes for indiana, update the stunt show and build a ride suitable, create somewhere for all the Lucas properties, I'd even be happy with a American graffiti diner.
Use TOT as a template for all future attractions, great queue, even better ride with a awesome gift shop that sells specific ride merchandise.
Pixar place gives off the impression that it's more than a 1 ride avenue, make it so, move pizza planet where it fits, give us the monsters inc coaster please, I'd also like to see wall:e in some capacity.
I love sunset blvd as it is but the BaTB show could go, put on a show using music from the likes of singing in the rain and wizard of oz and so forth, upgrade fantasmic, refresh it up to the standards that it should be setting not the standards it falls below.
Also, do something with the backlog tour, either bring it up to scratch or demolish it (along with LMA) and use the land to its potential.
