I read the 2000 post about not having 2 person scooters allowed and available in the parks. I was hoping to rent one for my Mom and Sister. Both have mobility issues and aren't up to the walking required to enjoy the parks. but My sister is also legally blind and can not see well enough to safely drive a motorized scooter or wheelchair. We pushed her last time in a regular wheelchair but none of us are up to that as she outweighs just about everyone and we have back problems. any suggestions or has anything changed in this area? thanks.
