I still do not know how people at the exit would be able to write anything on the GAC, and in most locations in
Disneyland, that is where a guest would be entering. The guest at the exit of any Fantasyland attraction dark ride, and indeed most CMs at the exits are not allowed to take their hand off the Emergency Stop (e-stop) button. They certainly would not be allowed to stop and write times down.
I understand CMWade when you said that the person at the line entrance would write down the wait time, but again, there is no one at the line entrance on most Fantasyland rides, and I cannot access the entrance anyway. Only if they were in a place all wheelchairs could access would it work, and there would need to be someone at end of line at all times.
There is no one at end of line for many attractions once there is overflow, or I cannot find the end of line, or it involves stairs.
So it would not save on labor costs - it would require more Cast Members. I also checked, and my wife confirmed when she was working any part of Splash Mountain except maybe FP return, she had no idea what the current wait time was.
Also, here is my way to beat the system, under your switched around system. I am using an average Saturday in the off season as a guide (the times I have seen posted for the last two weekends or so):
Let's say I want to ride Space Mountain - I ride Snow White, which has a wait time of 15 minutes. It is noon. There is no line of people waiting when I get there (pretty much ever). I am allowed to enter the next ride at 12:15. I ride Space Mountain, which has a stand-by time of 75 minutes. I am given a time for the next ride at 1:30. I then go eat lunch and rest.
I decide next I want to ride Star Tours, so I go on Pinocchio's Daring Adventures at 1:30, which has a wait time of 10 minutes. I am given a time of 1:40 to ride. I then to go to Star Tours, which has a wait time of 60 minutes. I can enter the next ride at 2:40
I ride that, then I go wait in the standby line for Buzz Lightyear, which has a wait time of 20 minutes. This queue is accessible, so I do not show my DAS. To the CMs, I am just like any other wheelchair user. They do not know I am supposed to be "in line" for something else. By the time Buzz Lightyear is done, my next ride time has arrived.
I go ride Jungle Cruise at 2:40, with a wait time of 30 minutes. I can enter the next ride at 3:10. I need the wheelchair boat, so by the time the boat gets there, loads me, cycles, and unloads me, 20 minutes have gone by. It is now 3:00. I now have 10 minutes to go to the bathroom, then present myself to Indiana Jones at 3:10, with a wait time of 70 minutes. This means my next entrance time is 4:20. I go right in, knowing this is a slow loader. It is usually about 20 minutes before I reach the ride, 30 by the time I exit. It is now nearly 5 o'clock.
In what I just described, I went on Snow White, Space Mountain, Pinocchio, Star Tours, Buzz Lightyear, Jungle Cruise, and Indiana Jones between the hours of 12 noon and 5 o'clock. I have also had time to eat and go to the bathroom. Technically if you add up the wait times for all the attractions for the stand-by queue that able bodied people use, the total wait time would be 280 minutes (I am including the waiting for Buzz Lightyear). This is 4.667 hours, or 4 hours and 40 minutes.
That means I have ridden 7 attractions between the hours of 12 and 5, which should have made me wait for all but 20 minutes of that time. And we all know that the combined ride times of the above rides is more than 20 minutes.
I will spend the rest of my day "leap-frogging" around the park, using my DAS for something with a very short wait in order to gain immediate or nearly immediate access to a ride with a longer wait.
This is my concern for what happens if they switched the system around. I already have to wheel in circles with the new system, so I would just keep doing it.
The DAS system as it is does not currently work right - yet. But it took me about 5 minutes of thinking to come up with a system on how to beat the "wait after" system. I know it should sound the same as the "wait before" but it does not work the same way. Right now the attraction I choose has no bearing on what comes next. If the system flip-flopped, all I have to do is put a short wait before a long one, and plan the "everything else" (shows where the DAS does not apply, food, resting in First Aid, parades, Fantasmic, etc) for the remainder of the "long wait" rides.
The current system needs to be tweaked, and there really really needs to be a system in place for people who have concerns beyond waiting in line - like those with vision impairments. Right now I am suggesting to people who need to be in a certain place due to a disability (front row, on an end, reflective captioning, etc) that they check in with a show while the
previous show is going on. Some theatres open very early (Magical Map in DLR up to 30 minutes before the show even starts) and there is no hope of getting seats near the front unless the guest is either literally first in line (families run to get up front) or they check in the show before, and ask that the front row be saved for them.
I am not certain how to fix the system - I do know that in DLR they need to make major changes to the system for wheelchairs at the top 9 rides.
I also know that I am not specialer than anyone else, and I should wait my turn, but I will not wait longer every single time - and it really is because of the wheelchair.
Perhaps they should have put off changing the wheelchair return system until the DAS was well tested.
