Traveling during spring break (yah, I know

) with my parents who are in their 70's. Mom will be renting a
scooter as she has trouble walking long distances (one reason we chose POFQ) and hoping to get building 4 or 5 (prefer 5). With that being said, should we be renting a car for going to the parks? We're only staying 4 days before going on our Dream cruise. Is it even worth renting a car? I mean, we'll have a scooter to haul around as well. I'm thinking it won't just be worth the trouble but wanted to get yalls thoughts. I haven't stayed at POFQ since 2006 and that was for a week. I've never done a short stay before and never with my parents who are elderly.
Any help would be much appreciated!!!
