Hello! We're going to be traveling this December to Disney World to stay with my extended family at Fort Wilderness. My father, in his 70's, has some mobility issues, so we have decided to rent a manual wheelchair (not an ECV) from an outside company for the duration of our trip. We're looking for the lightest wheelchair, and one that will fold up so that we can easily fold it up to take it on transportation (boats, monorail, buses, golf cart at the Fort, etc). We have never rented a wheelchair before, as this is our first trip with my dad since his mobility issues started. Can anyone tell me what company would likely rent the lightest wheelchair, and one that folds up? Thanks in advance for any help that you can give me!
