I think they might hold back rooms as well. I booked my holiday for this September last September and couldn't find any availability at POFQ. We were bummed as it's our favourite, but we ended up booking CBR instead, knowing they had some construction work going on that should've finished before our arrival. When we learned that the construction were delayed we didn't want to stay at CBR any longer, so I started pricing up upgrading to a deluxe and constantly checking POFQ. One day I found rooms at POFQ and there were more than one room available, so I think Disney must have released more rooms at that point. So just keep checking, and like others have said, you can always book somewhere else to make sure you get your free dining and gift card and then change/upgrade if it becomes available.
