I'm going to be traveling in March with my 85yo MIL; we have a split stay at Animal Kingdom Villas and Saratoga Treehouses. When I traveled in the past with my mom we used a resort wheel chair but that won't be practical for a split stay. I'd like to rent one that is very portable; with my mom we were able to fold it up like a stroller if needed and that helped on buses. My MIL is very petite so don't need anything big. Any recommendations on which rental provides a smaller lightweight manual chair? Thank you.
