For the first time in the 40 years I had made a visit to WDW, in 2019 I was forced to use a scooter. I can walk but only short distances before my back starts to scream at me. Likewise, I cannot stand either walking or standstill for over 15 minutes without massive pains in my lower back.
I dreaded using a scooter, but without it I would have had to stay home. To the credit of the guests, I heard no disparaging words and I was pleasantly happy and surprised about that. When I got more paranoid was, since the scooter fit in all the queues I could sit and ride it all the way to just before load. What worried me was that I could get off the scooter and walk relatively normally to board the ride. Since my problem had made me pretty much home bound for a year or so, I had also put on a little weight as well. But, to everyone's credit, either no one said anything or I didn't hear them, either way it worked for me. I had a great time and I know if it hadn't been for the scooter, it would have either been a very painful experience or it just wouldn't have happened at all.
BTW, just to insert a little reality into this... for those that choose to be judgmental about someone needing mobility assistance, up until one day, when I was 64 I never had a back problem at all and on that day I went from very mobile to my knees in pain in just one click of a second. This stuff can happen to anyone at any time, so keep that in mind the next time you decide to be judgmental or suspicious of another's, not always obvious, physical problems think about what it would be like if it happened to you.
