I've asked a question before on the wheelchair subject and thank-you everyone for the great advice. Now two more:
How much are wheelchair rentals?
and
Would it make more sense and/or save $ to rent one at OKW and keep it all week, thus saving time waiting in line each day at the parks?

We'll be driving our own rental car(s) to the parks bc we find it faster and more convenient....assuming the wheelchair will fit in the trunk. We're getting mid-sized cars.

Background - Our 21 year old daughter has a knee injury and she will be having surgery 3 days after our trip. We're getting a wheelchair bc walking is painful and a week at Disney would be really bad without one.

thanks in advance
21 more days!!!!
