I think it'll be baked into hotel costs and be tiered with quantity. "Hey Polynesian Bungalo guest, here's your 10 FP+ 180 days in advance! Mr & Ms All Stars, book your 2 FP+ a week before."[/QUOTE.]
Not trying to go off track any further but I see this happening soon. Or the "Extra Magic Hours" come with either an upcharge or only for deluxes/moderates. However, I think that your statement about the higher dollar resorts receiving more fast passes and earlier windows to book is spot on. It only makes sense for Disney as it would be a way to fill the resorts top down. I paid for the Unlimited Express Pass with Park Hopper for UNI/IOA this week but it's because I only have one day and want to make the most out of it. At least the UNI Resort hotels offer the pass as a part of staying.
Disney is trying to find every way to nickel and dime the visitor. I probably wouldn't mind so much if the parks had more new rides than once every ten years. However, that is a topic for another thread.
Sorry. I screwed up the Quote feature on this reply. Only the first part (the coherent part) relates to TestTrack. The rest are my musings.
