Our state offers an exemption and even just a cursory search showed a Maine application, my guess is other states have them too, as do the UK, Australia and parts of Canada (who knew.)
I also think the issues with clothes are a little underestimated. Some folks do have extreme issues clothes (to the point of stripping down "inappropriately"), but there are a lot options, and most people can find some cut or texture that works. But under WDW those kinds of modifications are excluded. (I do wonder how they handle ladies in burka. Do they have to raise the veil to prove they have on a multi layered mask underneath?)
As far as the union deal...I really have to question whether we'd accept an employment contract overriding ADA for other disabilities. If the Union contract says members should not be exposed to the risk of being bumped, hit and run over by an
ECV, would you be ok with refusing users from the park? After all, we all know quite a number of people, including CM have been injured. Public safety and all.
Ultimately our opinions on what WDW is requiring doesn't matter, and even if a case was filed, it would be years.... Yet I'm still disheartened. If people who have been there done that so easily advocate for the exclusion of others based on disability. ..well, its no wonder some of my son's peers have never even eaten at McDonald's let alone gone to an amusement park.
