I didn't think DCA was a mess during construction at all. We're local, so we were there all the time. I was actually sad to see the old DCA go, because it was our favorite park, mostly because it wasn't crowded. Now it's a mess.
If they do put the Indian Jones ride at WDW, I just really hope they don't water it down like they have with almost all other other attractions they copied from
Disneyland. Everything at WDW is shorter, has fewer special effects, and missing a lot of fantastic key elements.
I do hope that they put in more attractions, but it seems like lately when they revamp an area it is with one good ride, and a huge slew of dining, shops, and meet and greets.
