I generally like it, although much of the benefit gets lost if you park hop since the time window for the morning's fp may not have come yet when you switch parks and the new park may have the fp's gone for the ride you want. I wish there were a good solution for that.
How about a FP trading booth outside the back entrance to Epcot? I give you my 4pm FP for TSM in exchange for yours for Soarin as we switch parks!
But my kids loved their unused fastpasses for their scrapbooks!
