DAS is not a "free version" of G+. That's like saying that a trailer is a free version of a movie. Disney needs to correct that perception. Disney is a marketing behemoth and they're being outdone by some influencers without a fight? Not likely.
DAS has its problems, none of which are related to the definition of "disability" or, frankly, people lying about having one. I say that having a DAS person in my family who will continue to qualify under the new rules, the Universal rules, or a medical record requirement. I would vote to keep the expansive definition and correct the actual problems that are really creating the inequities that are appealing to the outright liars.
The first problem is advance selections. For most DAS users, candidly including my group, that's totally unnecessary. That should be an accommodation to meet a specific, narrow issue, that can be granted by a CM at their discretion. Not an automatic thing. I rejected these on our last trip and do not plan to accept these for our next trip. A good part of me wonders whether this was just intended to be a carrot to get people to register for DAS as soon as possible during the COVID years.
The second problem is the ability to do other things while waiting on the return time. Disney surely could incorporate a rule into its DAS technology/
MDE app that cancels return times if anyone in the group picks up a mobile order, checks into a dining reservation, uses an ILL, exits the park, purchases something, etc. - things you can't do in line. That would remove virtually all of the inequities.
The third problem is Disney needs to enforce its lifetime ban against liars to balance the risk/reward calculus. It's as plain and simple as that. If you brag on social media about lying to get DAS, it should be simple enough for Disney to figure out which Magic Band was used to tap in and ban that individual. For heavens sake, they are already publicly using biometric scanning.
If DAS users are required to actually wait the same amount of time to get a ride as anyone else, albeit perhaps in a different location, and miss all of the cool queue stuff that makes up a significant portion of many attractions in doing so, do we really care if someone is only arguably "disabled?" Are we so in love with the overflow lines snaking through Fantasyland at 2:00 that we must fight to keep them at all cost?
The new rules are a red herring, IMO. They miss the mark horribly and are not going to address any part of the problem. This makes me sad because it likely means even more overhaul to DAS in the near term.
