All I can tell you is that we looked at booking a trip this fall and decided against it. We're going elsewhere. A good part of that is because the cost is just so outrageous. I can take my family on two other vacations for what it would cost us to go to WDW. Now, I will also admit that part of our reasoning is for reasons I won't specify here but that the forum membership would pounce on and call me a bigot for and say I shouldn't care about. But, hey, I'm sure we're not the only ones acting based on such things either.
Regardless, though, the idea that everyone complains and no one will take their money elsewhere is, IMHO, false. There is a breaking point for everyone, whether it's because of cost, perceived quality, or some other reason. Disney may not have really felt it yet, but there IS a breaking point.
