I touched on this a bit in my trip report, but here is the longer version. I hadn't read anything about this system before our trip so I didn't know there was anything negative about it, but after dealing with it, we definitely had a negative experience with the first cast member we dealt with.
We were there with myself, my mother and father in law, my wife, her brother and his wife.My mother in law was in a wheelchair and the first half of our day we spent EE at DL and then went over to California adventure where she met us. We were able to use the queues there fine.
However, halfway through the day a problem emerged. My sister in law has a painful foot condition that makes standing for long periods of time unbearable. She is mostly okay if she is walking or in motion, but standing for her was brutal. She had to sit and take a break after a 20 minute wait for Soarin. Then I remembered that there is the new disability pass so we talked to the people at the guest services station by cars land and they directed us to guest services.
At California Adventures guest services I was really surprised by how the CM treated us. I am sure they get a ton of people faking illnesses for these passes, but they shouldn't be rude or condescending to guests as they never know if something is real or not. So first he asked us to explain what our limitations are. She stated what her condition was (it had a latin name, I cannot remember) and that it hurts to stand for long periods of time. He asked what our plan was in helping to alleviate things. She said that so far she is taking breaks, doing foot stretches, etc. He kind of looked at us funny and said, and what about a wheelchair?
My sister in law is on disability for a multitude of health issues, and her husband is a handyman, so she explained that they were on a very tight budget (and they were, we ended up giving them one of our gift cards). He then asked, what if he were to give her one complimentary for our trip. She said, well I don't think I would feel comfortable with that at her size. He starts going on about well you'll find after a while that no one is paying attention to you and it's okay. She laughs and goes no- I don't think my family will want to push me! I started busting out laughing and agreed- it was hot and we were all taking turns with my mother in law as it was. She asked if a
scooter was possible and he said he couldn't issue those complimentary.
So then she asks what her options are and he just kind of stares at us, like he STILL didn't even want to mention the pass. He actually mentioned having our group wait in line and her joining us as we got closer to the front!! Then he goes back to the taking breaks as an option and she just got a bit fed up and said okay and started to walk away. So at that point I stepped in and asked about the pass for disabilities. He said that could be an option, how many are in our party? I told him 6 and he said he needed to see them. I was confused about this but luckily everyone was right outside by Oswald's so we go grab them, wheel my MIL in and he says okay, they just have to visually confirm our party size.
So he processes the pass, takes her photo, prints it, explains how it works and then we left.
As far as using the pass, we didn't have any issues. She still took a lot of breaks, and it was great that Disney allows someone else in the party to run ahead and get a time written in, which saved her walking distances. The cast member would write down the come back time, which was the current wait time for the ride plus 10 minutes. We often found a bench to park at until it was time to go on the ride which helped her immensely.
Still, some rides had a bit of a wait longer than what was written on the card- Jungle Cruise was one of them. But there were some that we got right on and received dirty looks from those waiting in line (definitely happened on RSR)
Honestly, I don't know how she would have been able to enjoy the trip were it not for this pass and I'm glad she got it even though she was ready to give up.
Not sure if this is the feedback you were looking for, but that was our experience with it.
