The last time we were there, we did mobile at FFB. The actual line was all the way through the switchbacks and out the door. I pulled out my phone just to see if that was better and it was really quick. Put my order in, went to the mobile pickup area and didn't wait more than a couple minutes. Only way to go imo.WDW pushed hard on mobile ordering the past couple of years. During the two weeks we were there in June, we rarely saw anyone picking up at the mobile area. Most everyone was back to using the old tried and true order lines that moved very quickly. A couple of times the mobile areas were so dead that they diverted the line ordering guests to get their orders at the deserted mobile area . Keep it simple. The guests should come first without complicating stuff.
