Only had 1 day - yesterday - to visit both parks (with unlimited passes), got early admission with RPR and rode everything we wanted in both parks, saving Hagrid's for last. We got in the queue about 3:45pm, quickly walked to Hagrid's Hut, where the line came to a screeching halt, and would inch up every few minutes. We did this inching thing for every bit of 90 minutes before finally getting close enough to see the motorbikes. From here, the line went very quickly and we were on and off the ride by 5:30pm. The estimated wait was 150 minutes, so we didn't wait the whole estimated time, but only by a few minutes. Oh, and we absolutely saved the best for last.
