My guess is NO. Here is why: I believe that the reason Pop sold out so quickly for Free Dining, is that it was the most popular Value booked during the Bounceback and UK Free Dining programs, so not as many rooms were offered. No matter what, WDW will not make ALL their rooms Free Dining, they will only set aside so many, because they prefer you pay full price.
So if Pop was already near saturation for free dining rooms, and they want to spread people out a bit, they will offer more rooms in the AS resorts at the sale price to "fill out" those resorts.
If it is most cost effective in off season to run all resorts at 1/2 full, then they try to make all resorts 1/2 full, not some 1/4 and some 3/4.
Does that make sense?
Totally depends on which week you are going, but I do think over all, it will still be low season, but Disney has now guarenteed that the rooms will be "full-er" and that people will stay on site and spend $ on other things, because they are tied down by their ADRs.
That's my story and I'm sticking to it, because it helps me sleep at night and not have crowd anxiety dreams. LOL
