My 18 year old son has ADHD, anxiety, sensory issues and is most likely on the spectrum. He’s been going to Disney since he was three years old. With the old FPP system we never used DAS because we could manage on our own. If we couldn’t get FPP, he didn’t ride. We got DAS for the first time last August under the old system because I knew that he would not be able to wait in lines. I felt uneasy about it because he had been going to Disney for 15 years without it but without FPP, I wasn’t sure how we would manage. He nervously paced the room waiting for our turn with the CM. It was obvious that he needed it.
We just got back from our trip this week. I’ve used LL on trips without him. I know this won’t work for us with him for assorted reasons. This was our first time with the new online system. I was nervous because I knew his disability wouldn’t be as obvious on a video call. It was not an issue.
I requested my online chat around 10:30 am. It took about an hour to be connected. The CM was very nice and asked what the issue was. I mentioned his anxiety and sensory issues and was quickly approved. I even said we used to manage just fine with the old FPP. It really wasn’t an issue at all. All my son had to do was have his picture taken. He didn’t even have to answer questions which surprised me because he’s technically an adult. Five additional people can be associated with the person with the DAS, so a party of 6 is allowed to make the ride reservations.
I was then transferred to the next CM who would help with preselections. It took about 10 minutes of waiting. A few things to note :
1). You can only preselect for the park you have the reservation for even if you plan to hop
2). Rides with ILLs are not an option for pre selection
3). Choices were much more limited than I thought having started the process at the 30 day mark. You don’t get much choice, at least I didn’t for when we were going. MK was the most difficult which surprised me.
4). Once they are made, they cannot be changed. You will see them in your plans.
5). They have the same 1 hour window as the old FPP system and have to be used according to those rules.
6). They are completely separate from the reservations you make in the park so you can make a preselected reservation and still choose an in park reservation for the same ride.
We actually didn’t use many of our preselected ones. The times ended up not working out.
On the day you are at the park, you can make a selection as soon as you tap into a park. I put screenshots in my trip report if you want to see what the process looks like. Here is a summary of some things I learned:
1). You have to be in the park to make a reservation
2). You can make a selection during early morning hours for any ride that is open during that extra half hour
3). You cannot ride until the start time for the reservation but there is no end time
4). You can hold an in park selection and a preselected reservation at the same time
5). You cannot make another in park selection until you use the one you already have so no “stacking” like you’d use with LLs.
6). If a ride is down, you cannot make a reservation
7). The person with the DAS should tap into the ride first. It will turn blue which alarmed me at first. No worries. The CM checks the picture and then it’s approved. Everyone taps in and it’ll be green. If there is a second tap, order doesn’t matter and they’ll all be green.
8). If there is a second tap, you cannot book a new time until you’ve gone through the second tap.
This worked very well with my son and I. The entire family will be going in June. I will once again request a DAS. I believe the approval we have now only lasts two months. There is a lot my son won’t ride. BTMR is too loud going up the hill. He despises getting wet so Splash is out. He doesn’t like the looks of Pandora so FOP is out. You get the idea. We will have to plan carefully around what he won’t ride when making plans for the rest of the group so be mindful of the rest of your plans for things your son can’t or won’t ride. Obviously the person with DAS must ride to use it.
Finally, just know that sometimes, even using the LL, you can spend some time in line and if he has issues, you may still need to leave a line. We barely made it through 7DMT because as soon as we entered the building, it was so loud. That line actually wasn’t more than 5 minutes but it was loud in there. I convinced him to stay because I knew we were almost there. The good thing for me was that it definitely confirmed his need for DAS but the reality also is that sometimes it’s still not enough to manage someone’s difficulties. Be prepared for that too.
Hope my essay here helps 
I’m happy to help if you have any other questions.
but thank you for the suggestion. We used noise cancelling ear muffs on the plane. They helped but he still complained that he could hear and made it difficult for him to sleep which is what he wanted to do. I thought about bringing them to the parks but he used his ear pods a lot which did help.
That kid is a whole other adventure in parenting 
. Since he’s not planning on sleeping in line maybe the reduction in sound would at least help make the experience less annoying so he can get to the fun stuff. I wouldn’t recommend wearing them on a ride though, they could suffer the same fate as Ears and that wouldn’t be good.
