I'm going to chime in with what happened to me at UO last year; maybe if enough people publicly voice their discontent with the ableism at UO (and I despise that term, but it's incredibly accurate here) things will change. I was in Orlando for a week last August, and was incredibly excited to do UO - I'm a huge HP fan, and I hadn't been able to go since the HP lands opened. It was my first time doing a parks trip since I was diagnosed with Ehlers Danlos Syndrome. EDS is a collagen disorder that (among dozens and dozens of other symptoms) causes significant joint instability and dislocations. I was in denial about needing mobility assistance, and thought that UO's Express would be enough to manage the day, like it had been the last two days at WDW. Everything was great, until Kong. There was not a single employee visible the entirety of the two hour line. Because of the way the ride loads, there are long periods of standing still (which is primarily what bothers me in lines) followed by short bursts of movement. As soon as I started feeling the standing getting to be too much, we started looking for an attendant so I could get out of the line and leave via an exit (the queue is so narrow, you really can't backtrack). By the time we made it to the front of the line, I was sobbing, had multiple dislocations in each foot, and had displaced tendons. Trying to leave the ride, I couldn't walk more than a few feet at a time. My mother went to go get someone from first aid to help - it took the better part of an hour for someone to show. All they were willing to do was hand us a manual wheelchair and leave us to our own devices (that being said, the first aid guy they sent was actually semi-aware of EDS, which is INCREDIBLY uncommon, so props to him). Because of this disorder, I can't propel myself in a manual chair, so my mother WHO HAD A STROKE THE MONTH PREVIOUS had to push me all the way back to the car. And it sounds like even if I had an ECV last year, I would have been in the exact same situation. It genuinely ruined the entire day for me last year, made the rest of my trip that much more difficult because I couldn't walk more than a few feet at a time, and it's made it so when I go back this August I'm skipping UO entirely.
