This is an extremely offensive statement. As the parent of a child with Asperger's and a HIPAA certified administrative professional, I can assure you that HIPAA is very necessary to avoid discrimination against people with disabilities. Even if I were to provide "proof" (would her stack of medical records be enough?) of my child's disability, it would not tell CMs at
Disneyland what she needs, and a child with the exact same diagnosis might need something completely different. We don't use the GAC, we manage by using fastpasses and visiting on less crowded days to avoid long lines and crowds (although she did great when we visited in July a couple of years ago, she chose not to go with us this year in July), but I don't begrudge anyone else the use of a GAC, because their needs may be different than ours.
And if you think that parents of children who have developmental disabilities should just use "discipline" (as if we don't), you need to spend some time with special needs kids.
