Many years ago, when my son was 8 and was newly diagnosed with type 1 diabetes, I contacted Disney about any accommodations/what could happen if we had to leave the line, stuff like that. At the time, we were told type 1 diabetes doesn’t qualify for anything. So we were standing in regular queue, testing blood sugar before and after the ride (you’d be surprised how many people give stink eye for THAT! Honestly), and sometimes leaving a line if it’s too slow/too hot and his sugars started to drop. I have a lot of pictures that first trip of him checking sugars lol.
A few years after that, we went to Disney as a family trip. Again, type1 diabetes didn’t qualify, but my nephew did qualify as he has high-functioning autism. My sister and her family used the DAS system, but were only allowed 6 people per ride, and so they took my parents along with her family of 4. My family just did our own thing.
Recently, my sister went to WDW with me and my kids (July 2021). My autistic nephew was 21 years old, and she got the DAS system. The Genie+ wasn’t released yet, and the lines for rides were incredibly busy. TONS of revenge travel that time- crowd levels were 8/9 or so. Anyway, we were all able to go on the rides with my nephew, for the rides HE was willing to do lol. A lot of the time, he would just get to the ride, and say “Nope, not going” and that was it. This happened at Universal as well.
Anyway, in our experience, the DAS for him allowed us all to ride together when he felt up to it (that was precious- to have us all squeeze onto Splash was simply amazing), but he, as the DAS qualifier, really didn’t get too many rides in. He simply got overwhelmed by the heat and the crowds, so time in between rides they would go to shops, get a drink, get some AC…
In other words, clearly abuse of the system is a problem. But those who TRULY need DAS, what can they do? Get rid of the whole thing because of the bad actors? I know that my nephew wouldn’t stand in a regular queue-- the DAS line was about as much as he could handle-- and that was BEFORE G+, so the DAS line was basically empty. Now with DAS merging into the LL return lane, I really wouldn’t even recommend that they go to WDW again, unless there were another option for DAS riders.
