Speaking of my own personal experience traveling to Disney 5-6x a year, and staying in multiple hotels during each stay, almost always, if I am booking something under an AP discount when the general public promotion discount is ALSO out, if there are no rooms available under the GP promotion, there are no rooms available under the AP discount--which is exactly exactly what you pointed out as the only additional inventory of discounted rooms you were able to open were under the Florida resident promotion. Sometimes, AP-discounted rooms do pop up closer to the travel dates once the GP promotion has expired, but getting a discounted room that close to your travel dates is a bonus. In the case of the OP, I would never buy an AP JUST to get access to additional discounts as the inventory for rooms available at an AP rate is much less than the inventory of rooms available under a GP discount. If she's unhappy with the discounts offered under the GP promotion, she's certainly going to be really disappointed with the discounts offered under the AP promotion. An AP is not going to open up a whole other cache of discounted rooms for her to choose from.
