Wanted to chime in here. I have ADHD and have an access card, but it is for my POTS (Postural Orthostatic Tachycardia Syndrome). I have it because the blood in my body doesn't reach different parts of me, and I collapse, get dizzy and struggle for long periods of standing. I'm on heart meds, steroids and anti-spasm tablets and that illness is pretty debilitating.
When I got diagnosed, we really weren't sure if I would be able to work, be mobile, and do the things that I used to do (running). Going back to a theme park after getting this illness was a big thing because we weren't sure how the POTS would handle roller coasters. The access pass really took the edge off the visit because there was not as much queuing between each ride, and the booing system (not being able to go back on rides until the que time has passed) actually gave me a good bit of a rest between to recover.
It was really nice to be able to go to the theme park again as we didn't know that it would be possible when I got diagnosed.
That said, I can't see why I would need the pass for my own ADHD. I tend not to be able to focus so would prob ust be on my phone for the whole que. Not everyone with ADHD may be like me though and mine is pretty debilitating in normal day-to-day life.
