Under no circumstances is WDW having trouble selling tickets or booking rooms. They do not need AP's to lure people to stay longer or fill vacancy's. That is the entire point, they get nothing out of the AP program other than lost revenue. Every single one of those trips that is canceled by an AP will instantly be filled either by the previous AP owner or someone else and they will make more money in the process.
I think you grossly misunderstand the appeal of WDW around the country and world to assume they need AP's to lure people in.
It will be sunset and shut down like Magical Express and Disneyland AP's. You have my word on it.
