The problem in this thread is that there's a lack of understanding of the impact of actually having a disability and what that does on ones life in general. I think it was briefly touched upon but brushed aside earlier up thread. Generally speaking, it will put you behind the eight ball, so things like walking across the park, getting things to eat, purchasing souvenirs, going to the restroom, riding other rides, etc. are all much harder than it would be for those without disabilities. So getting the DAS may save you some wait in line, but by the end of the day, most people with disabilities report no significant advantage using the DAS system because their disability put them behind the eight ball and the not waiting on the queue was helpful (ands they're grateful for that) but not enough to give them any "leg up", per SE, because of all the other difficulties of their day.
Then you have other viewpoints from people who maybe aren't considering how disabilities might limit park touring anywhere outside of the lines, looking only at how you can strategically stack rides with DAS. Which on paper you absolutely could. You have two you can reserve before you come. You can reserve another when you badge into the park. You can get Genie+ and LL and then even stand in the standby lines for lower wait time rides and theoretically have one heck of a day riding all the big ticket rides with no wait. It's a valid thought process, too, because if you didn't have a disability that limited your park touring in any way outside of the queues, or if you didn't have a disability at all and were cheating the system, this would be a pretty significant advantage over someone who only hay Genie+ and LL. Or someone who had no extras.
Nobody is bringing the plaid coats into the conversation because those tours are expensive and DAS is free.
That's fair about it not expiring. That is pretty baller.
