No. Several years ago I was visiting with friends, and one of them had broken her ankle to weeks earlier. We had gotten there before them and went over to the car Rental and explained the situation. We tried everything available, up to and including a Cadillac and nothing worked. We had a total of six people in the group and the SUVs did not have enough room.
What we ended up doing for when we needed two
ECVs was a few people, including one with an
ECV, using Disney transportation and the rest driving. The only times/places we could go all at once was when we were going to a restaurant and I could do without mine.
