Maybe things have changed from 4 years ago. Notice Disney said these passes for prominent people given away for free "had no monetary value."
The larger points are
1. private and even public organizations sometimes grant preferential treatment to all sorts of people for all sorts of reasons, so it's puzzling anyone would reserve their anger and envy for those cases where the beneficiaries are disabled
2. within broad limits Disney and other private organizations have a lot of discretion in doing this, and it's irrelevant whether we think their decisions meet our own particular definitions of fairness or equality. They could give 1/2 price admission to senior citizens, or free Mickey bars to lefthanded people, or whatever. It's not my business - it's theirs.
