TroyW I hear you. I frequently need an ECV or wheelchair when I go to Disney because of my Fibromyalgia.
I've spoken many times on this forum about how rude people have been to me because they assume I'm just fat and lazy. If they only knew how painful the decision to get in that chair really is, how awful it is to be on the borderline where you're okay at one point of the day and then suddenly take a turn for the worse never knowing when that action that puts you over the edge will come. It's heart wrenching for me to make the choice to climb into an EVC, I don't use one at home but there I can better anticipate what the day is going to hold and where my limits are. At Disney, all bets are off. I don't want to be crippled, I don't want to have limitations, I don't want to be in that chair. But I'll be derned if I'm going to let my physical limitations keep me from enjoying Disney.
For a stranger to look at me, they wouldn't know that there is something wrong. Fibromyalgia give no outward signs of the searing pain, extreme fatigue, misfiring nerves, and cognitive fog that it comes with. My best friend and my husband can tell when I'm at my limits, but they're the only ones. The fact is, that you can not fairly judge anyone sitting in a wheelchair as "just lazy" you simply never know what is going on in their life or inside their body.
I'm not saying that there aren't people who get a chair "for fun", there are always idiots around. But I also know how gut wrenching and painful it can be to make the choice to use a chair at WDW. Random Tourists making assumptions about the state of my physical being and being rude about it, doesn't help. Unless one is some sort of medical savant, you just can't assume to know what's going on with another one. Kindness and compassion need to be the popular course of action. No calling them fat and lazy.
