I can strongly recommend Select Mobility Scooters

They are located across the street from
Disneyland at one of the Best Westerns on Harbor. Often if you rent from them you can also park there for the same price as the Disneyland parking structures and just drive the
ECV across the street if you only need to rent for a day, but they will deliver to your hotel as well.
they have excellent customer service (not quite as good as Gold Mobility in Florida, but it is up there) and they use the extended batteries in their equipment and keep their equipment in decent condition (again not quite the same level as Gold, but at least the batteries are in good shape and the scooters are not completely falling apart like some)
