When we were in Florida during Christmas and New Years of 2013-14, Fast Pass+ was just being rolled out (I think). We took advantage of the option, but then ended up changing our FPs throughout the day with no problems at all. Availability was really good.

We're going back in July, and debating on how much we want to pre-plan the trip. DH is convinced that we can wing it like we did last year, but I think now that FP+ has rolled out completely, we'll be hard-pressed to get on the good rides without pre-ordering.

Any ideas? We're also still kicking between annual passes or day-passes (we're staying on property, though)... which would make a difference, too, right?
