My biggest concern about the eventual (rumored) introduction of paid FastPasses is losing the ability to continue to get them after the first 3. We book our FPs in the morning so we can take advantage of continuing to get them, particularly on the "lesser" rides that our kids like, especially in Magic Kingdom. We'll go on rides like Barnstormer, Mad Tea Party, Small World, etc., grabbing FPs that are for the immediate timeframe. Once they likely limit them with paid FPs, I'm sure that will be something that we'll lose. All those rumors make me wonder why (or whether) they'll continue to have FastPass for those lesser rides. I'm sure they will since people plan those, not knowing better, but paying for a FP for Under the Sea is mind-boggling.
