Disneyland has definitely slowly gotten stricter over the past couple years. There have been more follow up questions / further explanation needed when applying than when I first started using
DAS. And this is for someone who was only trying to get it for myself + one guest to assist me so I can only imagine the pushback given to larger parties.
I would go as far as to say that DL was already slowly transitioning to this new limitation of what would qualify but that some exceptions were still happening since they didn’t yet have a process set up for alternate accommodations to fit those needs that they determined didn’t qualify a guest for DAS.
