I agree that no one knows IF this is going to happen, but it prob. won't suprise me if it does.
However- With Disney promoting the stay, and play, for $1500, is making a lot of people who thought on-site was too expensive, rethink their plans. I can think of 6 people, I work with, who are going because of this "deal." Every single one of them have been to Disney, before and know what it is like at the parks, just not the resorts.
I think that adding to many perks, to the more expensive resorts, after claiming that you can go for $1,500, is going to upset a lot of people. I can hear the "see I told you they were just trying to reel us in" comments now. "forget it, we're just staying off-site"
Disney has also introduced the fast pass, to all ticket holders, getting them used to it, and most liking it, and now, saying "WE gotcha" To enjoy that now, you have to not only stay on-site, but spend 2-3 times on your room.
My family is going 2 times this year. We can afford a deluxe, so the added perks might get us to stay there. But our trips, would be much fewer, and further in-between. I will def. be spending more, in my 2 value resort vacations, than I would be in 1 deluxe resort vacation. So in essence Disney might make more on the resort, but def. not the meals, sov., illuminations cruises, kids clubs, etc. that we spend. I know my family is pretty insignificant to the overall picture, but I'm sure others will have to make those types of decisions.
