I'm curious... I see these comments on being stuck 20, 30, 60 minutes... what would they do in the event that a ride stopped and a child seriously started freaking out, as in anxiety-panic attack? My son would absolutely LOSE it, and I mean he'd be trying to jump overboard if he got stuck in the dark. There is NO way he could sit there 20 or 30+ minutes waiting to be evacuated.
I'm guessing CMs will get there when they get there, and you will just have to sit there and wait?
I was on Great Movie Ride once when an elderly gentleman in front of us keeled over. People started yelling, and CMs stopped the ride immediately. We sat there for more than 10 minutes before EMTs got there. Very surprising and disappointing to see such a slow response. Luckily the guy just passed out from the heat and wasn't dying.
Sometimes there's only a handful of CMs working a ride, and it takes time to get everyone off. When we got evacuated off Everest, one CM came up and let us out one row at a time, and then led us down the stairs single file. Same thing when we got evacuated off Pinocchio, one CM walked through the ride, let out one car at a time, and led us out single file. I imagine if there is a kid screaming his head off, CMs would try to prioritize getting him off first, but I imagine they have a process and safety is first and foremost.
Another story, from Wedway, ride stopped for some reason. After about 5 minutes, a mother and son apparently decided they didn't want to wait anymore and climbed out. Of course, if the cars had started running while they were wandering along the track, it would have gotten ugly. Ride got shut down while CMs escorted them off the tracks (and hopefully from the park), we ended up sitting there 20+ minutes.
