Hello, Jennie! A few months before our family trip to Walt Disney World in 2010, my mother-in-law had transplant surgery. Although she was resistant to the idea of renting an ECV at first, it ended up making her trip much more enjoyable- I don't think she could have managed without it! Fortunately, Walt Disney World is one of the most accessible vacation destinations for those with mobility limitations, and you will have several options available to you.
Although Walt Disney World certainly makes it super convenient to rent an ECV at the Parks (and this is, in fact, what my mother-in-law did), I can understand your concern about availability, especially if you're not planning to get to the Parks at "rope drop" each day. Recently, Disney has teamed up with ScooterBug, which is an Orlando based Mobility Provider. Since they are considered a Disney Featured Provider, they can work directly with the Bell Services teams at the Walt Disney World Resort hotels to manage the delivery and pick up of your scooter, meaning you do not need to be present when the equipment is delivered. If you'd like to take a peek at their inventory or call them for information, you can contact them at scooterbug.com/orlando or (800) 726-8284.
Sometimes, however, it's good to comparison shop. Guests are still able to rent through third party companies, but just keep in mind that you'll need to speak to the vendor and set up at a time for a face-to-face meeting for the delivery in your Resort hotel lobby. There are a few companies that Disney recommends, including Apple Scooter, Best Price Scooters and Strollers, and Buena Vista Scooter Rentals.
You might also find the Mobility Disabilities webpage helpful, as it categorizes Attraction Access into three categories:
*Must transfer from wheelchair/ECV to ride vehicle
*Must transfer from ECV to a wheelchair
*Must transfer from ECV to a wheelchair, and from wheelchair to ride vehicle
Hakuna Matata, Jennie! I hope your upcoming Walt Disney World trip is worry-free!
