That's not what the ADA is about at all - it's not free services for the disabled that the nondisabled have to pay for.
You corrected your dangling modifier.
So if you are a family of 5, how does that work? 2 adults, 3 kids, one with
DAS, oops, sorry family, you'll never get to ride anything together. And wow, you spent a lot of time watching people in lines at guest services - how did you know they were all in the queue for DAS?
How would you know all of that, seriously? And you can't get past the CM with DAS access unless the DAS user checks in first and gets the OK. Then the others tap in. Sometimes there's a second tap in. And maybe they all had some other type of pass, like a Make a Wish, etc.
