And that is indeed part of the problem, for example someone with limited vision. Under the old GAC system, there was a stamp that told the CMs that was the issue. Attractions with well lit queues or outdoor queues, especially during the day were not an issue or some queues not an issue until a certain point while other queues were problematic. So, that stamp was applied differently at each attraction and maybe even differently at night than during the day at the same Attraction. For example, in a dimly lit queue, a cast.member would use a flashlight to guide the guest and their party, obviously they weren't going to have the CM go through and wait in the standby queue with the guest and their party, so at those attractions, they would go through the alternate entrance. For the well lit/outdoor queues, they would go through the standard standby queue unless they also had other needs (i.e. avoid stairs) that would prohibit it. When they changed to a
DAS system, those with low vision were supposed to simply be able to inform the CM at each attraction of the issue an get accommodated appropriately, unfortunately, this did mean constantly explaining needs throughout the day and many CMs refused to accommodate, so Disney ended up relenting and giving them a DAS because what can you do? This means that now those with low vision have a DAS and are going to be more.lokwly to use it on every attraction, even though it may not be needed on some attractions. Now some with low vision may or may not know which attractions it would be needed on, with the GAC system, the CMs could help with that if they didn't know, with the DAS, not so much, as a result, you end up with the person just being more likely to get a return time for everything to be safe. Please note this comes from DH talking with people who have low vision that have used both systems over the years and greatly preferred the GAC when it functioned as originally intended.
Perhaps they can setup the system where return times can be issued for attractions that the person would need it for, but not allow it for other attractions. For example, if a person needs shady place to wait, then you don't need for attractions where the queues are entirely indoors like Soarin' at EPCOT (at DCA, you still might since a large part of that queue is outdoors), but then there are other queues that are mostly or completely outside where you would need it. A similar concept could be used for those with low vision. I don't know if they will do this, but it could be done and would reduce the number of people coming into the lightning lanes.
