Wheelchairs that can fit go through the elevator and into the chutes with all the other guests. At the end, we roll across the front row and out the other side and down the ramp. My wheelchair, at about 24 inches wide, can barely fit going across the front row. ECVs and powerchairs, which are larger, cannot roll from the "entrance" side to the "exit" side of the ride vehicle. Therefore the larger vehicles like ECVs start on the "exit" side. Trust me - there is no way to get out the "entrance" side with any kind of wheelchair or scooter. I can barely get in! It is very tight, very very tight turns, narrow walkways. ECVs simply would not fit over there!
