Welp, no deal for me this year. I've got the dates I want and resort I want (Pop) and discount is not available for my dates. I'd be willing to change my room category, but they're all no availability. Well, Rack rate at POP is still less than anything available for my dates, and the only places I'd change to are POFQ (not available) or an Epcot resort (way too much).
The lesson I learned for sure, though, is to jump on the room I want as soon as the rack rates come out. At this point, I'm just thankful I've got a room where I want to be.
