I think a big chunk of the fault is on the guest but some does go to Disney. The thing is, I don't necessarily think that's such a horrible thing. While I think Disney is a magical place and can't wait for my vacation next month, one of the reasons I love it so much is because I happen to fall into their target market. And while Disney has a much larger target market than most people, they don't need to please everyone even if that was a feasible goal. They have guests who come from all over the world and they have a large group of people who have come to Disney in the past and who will keep coming back for a long time. It doesn't matter if there are people who only come once and never come back because there will always be someone to take their place. In fact I think Disney has reached a point where it's almost too crowded at certain times which is why they are making changes to even out things a bit, like the huge increase in AP prices.
However we are in the minority..

and not knowing that having ADR and FP+ are key.
