Somehow, I've managed to open a huge gap in my WDW knowledge.
I understand regular Fastpass. We've used it to our immense advantage, both before and after they started enforcing the closing times. (For anyone really new to it all, Fastpass is a free service that allows anyone-- staying onsite or off site-- to avoid a huge line at a ride. You put your park tickets into the machine, and it spits out a FP ticket, which gives you access to a MUCH shorter line within a limited time window.)
I've gotten bits and pieces of info on FP+.
But could someone lay out the differences between the "old" system and the new? When is it being implemented? How is it different?
Either a concrete explanation or a link to one would be greatly appreciated!
