I'm willing to put money down that people are only still willing to go because they have space mountain, big thunder, haunted mansion, pirates (which Disney is slowly ruining), splash (which they ARE ruining), etc. But even then, their terrible maintenance plan will make once peak attractions look like they need some desperate TLC, like we're already seeing with Dinosaur, Expedition Everest, ToT, and so on.
It's a very difficult scenario. Personally for me, going to Disney's California Adventure is now akin to visiting the dollar store. Disneyland is slowly being cooked to death, and it's both a sad and terrible thing to see.
The board and management in general should all be held responsible. They'll start getting the message with dropping attendance and overselling shares, if that ever happens.
