Are you speaking from experience?
I am not supposed to walk long distances but I never wanted to get a scooter for a cruise. On a Family cruise, for my mother and her BFFs 80th B-day, we rented them both scooters.
One night I borrowed one when they were asleep... I had no issues going down the hall... nice and slow, but when I turned toward the promenade, I accidentally accelerated too fast (much faster than any I had used before) and I nearly fell on my arse!!
I found out quickly why my mom wasn't thrilled to use it. But when I turned the dial down for her, she was much happier!!
