I would agree completely with Talking Hands.
I think you should rent an
ECV from an off-site company. A wheelchair would work, but pushing a wheelchair can get very tiresome, especially if you are not used to it. Also it depends on the weight of the passenger and the condition of the pusher(s).
Some information for off-site rentals are:

I have used Walker a few times. They will ask for a credit card and charge it the day before arrival. They will deliver the ECV to your hotel bell services before your arrival and pick it up there after your departure. Their rates, especially for longer than a week, are much better than Disney's. Also, their scooters are much better.
You don't say if you are renting a car or what. If you are using a car for getting around, the
ECVs break down into five pieces, the heaviest about 39 pounds. They take about a minute or so to take apart and about two minutes (once you are used to it) to put it together.
Another suggestion is find out your state's requirements for a temporary disabled hang tag and get the paper work and have your doctor sign off on it. The tag will allow you to use any of the handicap parking areas (which will be a necessity). Also, with the policy of charging for valet parking, with a handicap hang tag the fees will be waived. Also the valets will usually volunteer to assist in loading/unloading an ECV. In Virginia I printed the required form from the DMV website. When I took the completed form to the DMV Office it took less than 15 minutes from the time I walked in until I had my tag.
An ECV will give you the freedom you need. You might want to go ito a major grocery store near your home; many have ECVs available for use within the store so you would be able to get used to one. Just realize the rentals are smaller and MUCH more maneuverable than the one in the stores (faster too).
