Looking at historical data- they roll out the free dining in stages- so even though it's been reported as only for the Disney Visa card holders at the moment- and only through Sept there is still time- Disney may still roll out some discounts for Fall for all.
The only caveat I can see it that lots the Fantasyland expansion is scheduled to open this Fall and Disney is seeing no need for discounts b/c they "built it" and now people "will come" discount or no discount-- not sure I agree with this logic- but it may be what Disney is thinking-- people will pay full price for rooms, and dining, and tickets and not complain b/c they want to see the new Fantasyland. Ummmm... not us.
We'll see, I am still hoping for some kind of discount for Oct/Nov- free kids, free dining, 30% off room, buy 4 get 3 free... etc. SOMETHING!!!!! Please Disney don't let me down. No discount, no staying on property for us- we'll take advantage of the "cheap" offsite accommodations for less-- just the way it is. Dh would rather stay at Marriott Grande Vista or somewhere similar for half the price and double the luxury anyhow.
