After reading through the last few pages, I wanted to make the point that WDW appears to have really driven away locals. Earlier in the thread, I mentioned how when I went to SeaWorld earlier in the month to preview Penguin Trek, the park was incredibly crowded when compared to what I've been seeing with Disney and Universal this summer.
I just got back from Tampa after previewing the new coaster at Busch and again, pretty crowded for a Thursday, but checking wait times at Disney, it's pretty dead. I even made a detour through Disney property because I4 was so backed up and I passed by the MK parking lot which was remarkably empty.
Not only is travel from tourists down for WDW significantly, but it appears that SeaWorld is scooping up a lot of locals that no longer find Disney interesting either. From my observation, Universal seems to have seen a general attendance slump this summer as well, but I think that's because there's usually so much crossover with tourists visiting both resorts. It'll be interesting to see just how much Epic changes the equation for a lot of people.
