Like @
HMF said, it depends on what you mean when you're comparing DCA and DHS/DAK. DHS needs to finish changing its back half from a production facility to a theme park. DAK needs to un-water down its headlining rides (Safari, Everest, Kali and Dinosaur are all worse than on opening day) and fill in expansion pads.
There's some quote that gets thrown around that Walt Disney may or may not have said to the effect of "once you lose someone, you spend twice as much money getting them back". DHS and DAK have some "meh" to them, but DCA was toxic. DCA was uncool. They had been adding things piecemeal to DCA since opening, but it didn't make a dent. Here's my (to the best of my ability) list of the additions to DCA since opening day up through Midway Mania (which was budgeted before the giant makeover):
-Who Wants to Be a Millionaire - Play It! (new build)
-a bug's land (new build)
-Tower of Terror (new build)
-Toy Story Midway Mania
-Aladdin: A Musical Spectacular (new show in existing theater)
-MSEP (old parade brought back, but rehabbed)
-Block Party Bash (new parade)
-Pixar Play Parade (new parade)
-Turtle Talk with Crush
-Monsters, Inc.: Mike and Sulley to the Rescue! (rethemed ride)
-Playhouse Disney - Live on Stage! (new build?)
plus various smaller attractions like your High School Musical stage show things and whatnot
I know some of those specific attractions will draw groans, but if DHS or DAK saw that
level of investment over a seven year time period like DCA did, I don't think we would be complaining much about either park.
