Anytime Disney has to provide special accommodations to a guest, that uses Disney resources that could benefit all guests. The more guests that they have to give special accommodations to, the more resources that are used. That is one of the reasons why the GAP is out of control right now, just too many people using it that really shouldn't be.
I know I am being harsh and will be neg repped and called a jerk for saying this but at a certain point I (and I'm sure many others) just get a little fed up with the "p***yfication of society. It's ironic in that we have a park that celebrates the incredible bravery and self sacrifice of people who pioneered the west, explored space and a courageous statesman who freed men from bondage. But that same park has to offer special accommodation to a person who can't stand in a line without going into an attack for fear of honey bees.
