Renting a scooter

We need to rent a electric scooter for my mom while we are at Universal. Instead of getting it in park, I think we will rent one so that she has it all the time to limit her walking. Does anyone have a company they rented from in the past and liked?

We rented from Apple Scooter a couple of years ago. We liked the scooter and service. I plan to rent from them on a June 2016 trip.

Buena Vista have been recommended to me.
