I think I understand what you are trying to say but simply wanted to clarify that "for any reason whatsoever" is an overstatement. I'm sure you didn't mean it this way but Disney cannot violate anyone's civil rights.
Furthermore, I don't want to get into a DAS discussion here but it's possible that this trial run might violate the American With Disabilities Act (ADA) if it does not honor DAS. After all, Disney has stated that DAS complies with ADA, suggesting that not honoring DAS is a violation of ADA. Hopefully, someone consulted with Legal before OK'ing this trial run.
