we did our first test of fp+ w the magic bands at the end of october and where we use to risk getting stuck behind someone getting a bunch of paper fps like you mentioned now you get to wait twice as each person scans their bands (once at the entrance of the ride and the second time where the regular and fp lines merge...now you either get yours to swirl until it turns green (best case scenario) or you stand behind someone who puts band up...nothing happens, cm tells them try again, maybe it finally swirls and changes green maybe not (= more instruction from cm), then their kid gets there and it takes more than one instruction on stand still, put the head of mickey from your band against the scanner...etc...you get the idea. At one point we had a cm just waiving people through on btm because the fp line was backing up so bad. much quicker when they just took the entire groups paper fps from the first person in the group. i'm ok with the basic idea of mb and fp+ but not how it's being executed.
