I think this post is spectacularly out of line. To say someone is a liar is truly inappropriate. And, in fact, the GAC was NOT a FOTL/unlimited fast pass.
I and several of my family members have varying (visible, invisible, mobility, non-mobility) issues that affect our time at the parks. For years, I didn't need to use the GAC, or a wheelchair. In recent trips I have used both, as has my family. This (early "low crowd") December was our first experience with DAS.
GAC was, for our family, vastly superior to DAS. It was never "Better" than being able bodied and standing in regular line, and it never afforded us more privileges than those who did not use it. It was NEVER a FOTL pass, or an unlimited fast pass, as the person I quoted above seems to think.
Depending on what stamp/accommodation was on the GAC, some with the GAC were NOT ALLOWED into fast pass lines without actually getting fast passes like everyone else. Some were, but may have waited longer in different areas (to avoid crowds, await a special vehicle, bypass stairs, wait for a cast member to let them into a separate line etc. Frequently, although we did usually access the FP line with the GAC, we waited longer than the FP queue time, given constraints like those listed above. It did NOT provide FOTL or a shortened wait the majority of the time. It did prevent us from having to (with limited mobility and stamina) cross the park to get a fast pass, go to another attraction while we waited, and then walk back to the first, FP, ride- a LOT of unnecessary strain. It also allowed CM to see accommodations we needed.
The new DAS failed our family on both those counts. With having to go to an attraction to get a return time, and return to the attraction later (vs just entering the FP line) it necessitated a lot of crisscrossing the park. After doing that once (Get a time, go to a ride with a standby line uncrowded enough that DS9 could handle, cross back to original ride) I A) had to rent a wheelchair and B) couldn't do it any longer, so I just had to entertain antsy kids during the entire DAS wait. That situation is fine, and something I had to do while waiting in alternate areas with the GAC, but the problems came when all of a sudden SNDS9 changed his mind about what ride he wanted to do, completely melting down. With GAC, we would have simply gone to the new ride he wanted to try. With DAS we were stuck in a queue with nasty judgmental people (not safely to the side as allowed with GAC) of the ride for which we had gotten a return time.
Additionally, with the DAS, when the wait was 20 minutes, a CM refused to give me a return time and indicated that I should just go in the regular line. The issues we face are exacerbated by crowds and tight spaces. Having a so-called "short" standby line time does not change that fact. But unlike GAC which clearly indicated an alternate entrance, not a "short line," DAS makes no provision for this. DAS was similarly unhelpful when I needed to explain the need for captions, for front row seating, etc.
As for the FP+, we had carefully planned ours to supplement the DAS. Until SNDS9 had a migraine that landed him in the infirmary for 3 hours, blowing our times out of the water, and leaving my husband to struggle to reschedule them with an unresponsive app. For example, he rescheduled one FP+ but then I couldn't handle the mobility challenges along with the other children while he was in the infirmary, so it didn't work. Rides near me either didn't have FP+ or they were no longer available. CM had told us to use FP+ for parade seating, so we used one of our options for that, only to find that come parade time, they had not set up a FP+ area that day. The app crashed many times, making adjusting our FP+ schedule so difficult that we finally gave up. There is nothing equal about DAS.
And while I certainly agree that Disney doesn't owe me or my family anything, it saddens me, as DVC and annual pass holders, staunch advocates of Disney for it's therapeutic effects on my SNDS9, that based on this DAS experience during a low-crowd time of year and it's nightmarish results (especially in comparison to how we were able to cope using GAC) we will no longer make Disney our go-to place. We are selling our latest DVC VGF acquisition, we did not renew our premium annual passes, and we have no Disney trips planned for the later part of this year. It deeply distresses me and my family, as we were not able to merely "Suck it up" and deal with doing fewer rides as the person quoted above suggests. OP's observation that Universal does allow express line access while waiting offers a glimmer of hope, and I appreciate her sharing.
Unfortunately, being both Pooh-sized and having other physical limitations, the rides at Universal are less accommodating. However it is still something to consider. i hope this lengthy post helps someone as they try to figure out how DAS works vs GAC in real experience, and perhaps reminds posters to be kinder to one another.
