Yes, cost is a big difference-I rented a WDW scooter on 3 separate days, then the next time I rented for the entire week from an outside vendor for about the same price. The other difference is BIG-I mean size. They say the bigger, the more comfort. Not true with WDW scooters. They're kind of like trying to negotiate with a huge tank in a small parking lot. I don't know how people get through some of the twisty-turns in lines.
