I'd love to know how many people unhappy about the change stay onsite. For us, the ticket price practically IS the price of going to Disney. Having toured the DVC resorts and checked out a unit, I know I'm not staying onsite with my current entourage ever, and staying offsite costs us less than many another trip. We're not big shoppers and even in terms of my pin collecting I mostly buy Disney discount or wait to pick up specific pins off E-bay, so that cost is negligible. Only two of us are really into Disney food and even then it's only a snack here and there and maybe a CS lunch or two a week - which, again, on par with or even less than our spending elsewhere.
But since we're not into world traveling, hate cruises, don't ski, don't do amusement parks, and can travel off season for most potentially pricey vacations we want (beachfront in September is just as warm, much less crowded, and costs considerably less), Disney is an usually pricey vacation, and that price is the tickets (youngest is now old enough it's adult tickets times 7, in our family's case).
So for us, and I would guess for a lot of people, a change in the
ticket prices is a real sock in the vacation budget, and a definite reason to consider vacationing elsewhere. If it was just hubby and I, or if we were traveling with just little ones then, yeah, there are a ton of deals Disney offers. Not surprising, since that's the group Disney's aiming at.

But you gotta stay onsite to take advantage of most Disney deals, so for someone off site, changes in ticket prices are a big deal.
Personally, I'm much more cheered by pertinent cost-per-hour comparisons, for which I thank everyone who posted.
