Get stuck in line with an autistic kid during a meltdown. Yeah. I have no problem letting them ahead of the line. And it's not their fault, they really can't help it. But it gets UGLY. And I feel bad for the kid's parents. And before we get the, "well, the parents should do this or that..." We can let them have a pass to have a good day. It's not the end of the world. I don't understand taking infants to WDW. But people do, and they're allowed, and it's not my place to say otherwise.
I don't look at it as an etitlement. If someone's average day is basically half of what I'm able to do, again, I have no problem letting them ahead of the line, because I view that as making it equal, not better.
I am changing my mind about the scooters, though. I've given a lot of them a pass with the fact you cannot determine what someone's disability is my the old eyeball test. Having said that, and at risk of being a hypocrite... My father uses a wheelchair at Disney, and looking around it sure looks like a majority of the scooter people are using one because they don't want to walk. The CM's (it's funny, you want to see them break "character" bring up the scooters) I was told by one who was helping my father that they rarely help people in wheelchairs anymore, it's all scooters and they can be absolutley horrible. They actually appreciate helping people in wheelchairs now. And just the eyeball test, there seems to be a whole of them who are able to transfer to ride vehicles, very easily, whenever it suits them.
