Waiting in a confined space, unable to move around freely, is what causes many people with autism the extreme distress that the DAS is designed to avoid.
Sure, a calming room with sensory toys will help some people with disabilities. It does not follow that it will be “more accommodating” for all.
But clearly several posters here think all people with disabilities are the same. Perhaps you’d all be happier if we went back to the days when they just stayed at home, hidden away, and never went anywhere where they might cross your paths. Or even “looked after” in institutions.
