At one time I had to rent one due to leg injury got mine at the main entrance so it was easy to return there. I believe most companies have more than 1 rental/return places.
They have scooter rentals right as you walk inside the front gate
There are several rentals around , best whenever you park and get to a building just ask. They have different prices also, but don't rent one of the smaller scooters with tiny wheels.
