Hi, Tom!
Here's what Sue posts for off-site providers for
ECV's. Power wheelchairs are different because they are only rented to people that have one already because they have to be programmed for each individual.
A big advantage of renting from an off-site provider is that you will have the ECV at the resort, Downtown Disney and from the buses to the parks (which can be a long, long walk).
Any other questions, just ask as everyone here is so incredibly helpful!
