My best friend is a supersized person (400+lbs) and is meeting us in Disney. She had rented a EVC for her trip due to her doctor not wanting her to walk becasue of a large herina. I am worried about battery life, since she is so heavy. She rented a heavy duty scooter, and i wonder if it could be plugged in durring meals or something? Will it be harder to get it on buses becasue it is the heavy durty weight model? SHe has not ridden a scooter before (and hopes its like riding a 4 wheeler, ha ha). Any tips would be great (didnt know here to post this)
