Given the level of abuse the system was seeing, something needed to change. And while some might argue the changes were inappropriate, I can guarantee that any system any of us could come up with would not be perfect either. Given the stated goal, the choices seem reasonable. I suspect we'll see some changes over time.
This is 100% the issue right here. And what generally happens when you have had a system that has been grossly broken for quite some time (going back to the days where there were "tour" guides that would attach you to their DAS and get paid to accompany you). You go off the deep end the other way and limit it too much. When we attended a couple after hours parties that were up charge events, there were DAS folks literally going on an attraction, turning around, going back through the Lightning Lane Line (DAS) and riding multiple times as we sat in line and watched. One of the many upon many times I have seen this system abused in the past. I have absolutely no issues with there being accommodations for those that truly needed it and there should be, but I believe that possibly those (not all) that were/are making the most noise about this are those that likely didn't need this consideration, they were folks avoiding the paid upcharge of Genie +/Lightning Lane. This is also why I think they took this out of the hands of normal guest services because Disney knew the reality of what was going on. There will be changes as they get control of this, but of course they will not be immediate. For heavens sake there were You Tube videos out there that promoted getting approved for DAS to be able to bypass the upcharges.
I know that this doesn't apply to just DAS users, and I realize that some (those that need it included) are trying to avoid the upcharge, but putting the time into doing the research into how to best utilize the paid system, and I am not talking the fancy Premier Lightning Lane, just the plain/old G+ is well worth it. We run "Theme Park Challenges", if you google "Every Ride Challenge" you will see what some crazies like myself put ourselves through. Just recently we rode all 55 Attractions at Disneyland/Disney California adventure in not only an operating day, but in less then 13 hours (not hard to find me on the Every Ride Site if you look at my Handle here), using absolutely nothing but Paid Genie Plus (not the premier) and using one Individual Lightning Lane. Do I wish the old Fastpass Days came back where we could select our lightning lanes like 60 days out with a resort reservation (WDW) were back, 100%.
The reality is that Disney and most attraction operators will continue to charge more for less, and a paid "skip the line" environment is here to stay. If you absolutely refuse to pay it (which I don't blame you, and understand) then you will wait in line longer, not only at Attractions, but at Airports, Zoo's, parking etc etc. That's just the world we live in, disability or not.
