She can ride the
ECV all the way to the boarding area.
You use the regular line and when you get to the large room with movies playing where people wait in queues to be allowed into the loads room, stay to the far left. Dont enter the queue inside the room.
2) stay in the ECV and transfer to a ride car. They will show you where to park the ECV. If that is too far for her to walk, tell the CM, so they know what you are doing. She can pull it up as close to the ride car as you want and someone else in your party or the CM will move it after she loads. For most people who can transfer, this will be an easier transfer. There is a little lip to get over into the ride car - less than 2 inches.
