I have a disability that is unusual and only really prevents me from using 4 lines (3 at Disneyland and 1 at DCA). I asked if I could be allowed to use alternate entrances for those 4 attractions and was told by the CM in guest relations that I needed to send my group (which was just one other person as I was there in a group of 2) through the regular line and then join them when they got to the front of the line by telling the CM at the exit that my group had waited in line without me. When I got to the attraction, the attractions CM told me that this not possible. I ended up trying my luck in the regular line and after waiting about 45 minutes I was having such a bad reaction that I told the CM at the front of the line I couldn't ride. They let me out a side entrance and I went home earlier than planned. I would appreciate any advice on how to communicate with CMs. The one I spoke to did not seem to understand my issue and how serious it was. I'm also wondering why they suggested I wait for my party at the exit when this doesn't appear to be allowed on most rides. Although I have had this condition since high school, it has only recently gotten worse so this is all very new to me.
