Yes. I have disabled access. Before I haven't really used it but now lately I am using it because I have added problem with standing for more than short while. It is normally not covered because I haven't gotten any paper on that but I am able to use disabled because of my deafness.
I was in particular bad state when we visited disneyland paris that we had to rent wheelchair for me. I did notice large difference in attitude, both from other people and by the workers. By the workers, it is all about no unneccessary standing etc. But when I am not having wheelchair attitude is very different because they do not know about my feet issue so I can get to wait standing for up to 1 hour anyway. For example Thorpe Park Nemesis "fast pass" last summer. I wasn't too thrilled.
Disneyland was better because of separate fast pass and disabled pass ("cast member") But with that said, DL Tokyo was a little less good, I think because of different company running it. Or yeah, I did not have wheelchair then.
At home here I am more ok because then I am home and I can be home for days and have fresh feet. On vacation I am expected to walk around (shops, sights, museums, etc...) plus the walking to/from commute. (too expensive to do taxi everyday!) so every day much walk = feet destroyed much soon.
I have yet to figure out why my feet are like this. I have gotten special orthopedic soles molded after my feet. I have 1-2 cm high arches (clearance from ground up to the arch "ceiling"). I thought the soles might help because of that, but apparently there's more than that. When I am in pain the whole foot "glows" of pain. Standing still (in queue) is 1000 times worser than walking (hobbling, haha).
