Think about what Disney does for those with disabilities (and Disney does *a lot*). Well, most of that is mandated by the ADA. And so, there are legal mandates for inclusion when it comes to people with disabilities.
But that's different from 'courtesy.' If there was no legal mandate and Disney didn't want to do anything out of the ordinary for people with disabilities, then Disney could very courteously say to people with disabilities, "Oh, so sorry, we can't accommodate you." That's being courteous while being excluding.
But for Disney, only safety outranks inclusion for people with disabilities.
"Inclusion" is a reminder not to be exclusive and discriminatory.
