Thanks for your reply! I had read a 'sticky' in this forum which gave me the information that they rent them there (listed below - I hope!) but maybe the 'sticky' is not accurate.
Wheelchair/
ECV/Equipment Rental
--------------------------------------------------------------------------------
ECVs are also called electric scooters or power scooters. They are 3 or 4 wheeled battery powered mobility devices. They are usually steered with a tiller (sort of like steering a bicycle).
At the parks
Wheelchairs and ecvs are available, first come, first serve at all parks. They may not be reserved ahead of time.
There is a pretty good supply of wheelchairs, but ecvs are in limited number and frequently are all rented out by mid-morning. Guests must be at least 18 years old to rent/drive ecvs.
Ecvs and wheelchairs may be used only in the park where they were rented. (You can't transfer them from park to park).
If you are planning on returning to the park or visiting another park on the same day, keep your wheelchair/ecv deposit ticket. This will allow you to obtain another wheelchair or ecv, if available, at the next park at no additional charge.
If you plan to return to the same park later in the same day, Ecvs can sometimes be held for you when you leave the park.
Length of Stay rental ticket for strollers and wheelchairs allows you to make a one-time payment for as many days of rental that you will need. Upon visiting a theme park, show your receipt at the stroller/wheelchair rental location and you will be directed through the queue with little or no wait.
