My Mom used a scooter service, which was wonderful for her and her health issues (bad arthritus) whereas she really couldn’t do Disney unless she had a scooter. There are a couple of downfalls I just want to point out in considering using one.
Very hard to manuever in crowds. No matter what you do to try and avoid running into people, it’s just going to happen because everyone walks in front of you. So that may be a little stressful. Also, getting the scooter on the buses. My Mom was not comfortable driving and parking them on the bus, so I had to do it for her each time. If your Mom wanted to come and go as she pleases, would she be comfortable with getting on and off the bus herself. Also, the battery life. This could have been just my Mom’s but they said the battery would last all day, but hers seemed to konk out maybe an hour before she really was ready to be done for the evening.
Not to be negative, because the scooter has allowed my Mom to enjoy things she definitely wouldn’t have been able to, but just wanted to point out some facts.
