I'll just say that I do go plenty of places that can be challenging for me but not impossible without asking for the accommodations they make available, especially if there's a quiet area I can go to if I get overwhelmed. WDW is a special sort of challenge, for I think pretty much everyone regardless of abilities, and while I can and do go on rides without DAS if they have a posted wait time of >30 minutes (I'm usually good to around 20-30 minutes before hitting overload, unless there's something like a malfunctioning light in the queue that's strobing), I'd definitely have a return time booked for something else while I'm doing that. Honestly, I often hit the return queue as much as an hour after the window because there were other things I was able to use the standby queue for on the way there or we got hungry and stopped for food. The thing is, that I can only do that because the accommodations that Disney offered give me enough peace of mind that my overall stress levels are low enough for me to enjoy most of the park in a way that is closer to a typical guest. The new alternative accommodations may be sufficient to get me to that point. If they are, I'll be happy enough to just buy the Multipass thing if I can't get DAS anymore, but I won't know that until I can actually try them out myself.
