It may interest you to know that in europe & Disneyland Paris in order to "benefit" from their disabled accommodations you have to show your blue badge to a cm who then issues you with a disabled persons card. European blue badges have the photo of the holder as an integral part of the badge & they must be present.
This card acts like fastpass in most cases allowing you to book a timed slot much like Disneylands system. However the main difference is that it is only good for upto 5 people including the disabled person for rides & the disabled person & one conpanion for reservered parade & show areas. I have seen bigger families have to split up as the cm's are usually very strict.
No bluebadge no accomodations! This applies even for people suffering from obvious disabilities.
There are no problems, no one throws a hissy fit & everyone understands that if you have the card you have had to show a legal document, I.e. your blue bage, to gain it & treats you accordingly. I believe they will also accept a Dr's letter for temporary conditions however they can & do check if they are legit.
Absolutely minimal abuse & even if you are in a wheel chair or ecv if you cannot provide evidence of your disabilities you don't get any additional support. Woe betide you if you leave your card back in the hotel.
Now I understand that in the USA the rules are different, but that very fact is actually making it harder & more unpleasant for people who need genuine support.
I don't want to be disabled I'd love to be fit again & I don't know a truely disabled person who feels differently & yes most of us struggle on, causing ourselves more pain & actually compromising both our own & our families enjoyment just to avoid that look. As a british veteran who isn't obviously disabled, until you see me try to walk, & unfortunately who is far heavier than she would like, a direct result of the drugs I have to take to control my condition I've seen that look many times. Can I suggest that perhaps we give everyone the benefit of a doubt & consentrate on our own holiday & unless someone is being deliberately obnoxious, which lets face is not restricted to possibly disabled individuals, just go with the flow & thank whatever or who ever you believe in that its not you who is affected.
