There is a weird amount of , " What about me ism" in this thread. So many posts Is ring with an air of, "Well I can't do that thing, so it's not fair the disabled person can." That is such a weird take to have.
The disabled person might have physical or mental limitations that proclude them from riding a decent number of rides. So, what does it matter if they choose to ride the three or four over and over again that they can.
They might also only be able to be in the park for a limited number of time directly related to their disability, so what does it really matter if they can use DAS for 1 really long line, while waiting in two or three shorter ones in the mean time. I know that I cannot do the same thing, but I also have the option to choose to be in the park for twelve hours that day with minimal impact to my health.
The better way to take these discussions is when somebody comes in concerned about how to prepare, Advice is given. Or when somebody is denied and doesn't know what to do, Advice is given.
Arguing about the would of, should have, could've of what disney should have done might be more fun, but is definitely more fruitless. Thay have made their decision regarding DAS for now.
