Disclaimer: I’m only sharing my experience with my daughter who has autism and not speaking for others or implying anything about why others shouldn’t receive the same accommodations as her.
I don’t think autism will automatically mean that you get
DAS . I think you will still have to talk to someone and they will decide what accommodations you will get. A leave the line option might work for some people with autism so that is what they will receive. In the case of my 4 year old daughter who has autism and a global developmental delay with severe speech and communication delays, that would not work. If she can see the ride, she screams and cries and has meltdowns the entire time we are in line, so we would be leaving every line we got in. She is also an eloper so that is an issue too and she becomes easily overwhelmed when trapped in by people. Once she has something in her mind, it takes a very long time for her to calm down, sometimes an hour or more. You can’t reason with her because she doesn’t fully understand what you are telling her. So, getting out of line to calm down and coming back to the line wouldn’t work.
We just went to Silver Dollar City and using their disability access pass makes me feel so awkward because you are the only people going in the exit. The ride attendant has to stop loading people to give you a return time and fill out your paperwork. Then when you return, you are the only people entering through the exit, the ride attendant has to stop and fill out your paper work again while everyone in line is watching you get on the ride first and wondering why. I’ve had people ask me about it too. I get so embarrassed so I don’t use it for her there very much. If a line looks like it is 20 minutes or so, we will wait in the regular line, but i spend the entire 20 minutes trying to keep her calm and corralled. I can tell everyone around us is annoyed and it is mentally and physically exhausting for both of us. DAS is the perfect solution for her because she waits where she can’t see the ride and moves faster through the LL so feels less enclosed. I agree with someone else that they probably listed autism specifically because of the court cases that involved DAS and autism.
