We used the wheelchair access for FJ. We went through the normal line and was taken out of the regular line to board the ride. This happened right before the sorting hat. We had our own 4 person bench which is stationary until we were secured. The bench is then inserted into the main ride line. When the ride is over the reverse is done. The TM members that handled us were great. You will not feel rushed. We were there on June 22 and it was crowded.
