My trick at Animal Kingdom is to book the Na'vi River Ride at 7:20 PM, ride it, grab a beer, and get in line for FoP just before closing. They have to take you if you get in before 8:00 PM. The should be about 1-2 hours, and remember 15 lines of that is a show that keeps you entertained anyway. Short of that, if its really that important to you, After Hours is $125. That's a way to get some really short lines. Probably more economic than overpaying for Disney hotels to get a jump on the FP+'s.
