I got stuck on splash (thankfully not before the big drop!) but a CM came by and got everyone off then we walked along the side to an exit. It only took like 5 min and there was a few bunches of people and it was really organized. Another time I got stuck on Indy, the lights came on and we were stuck for a few min, and started going again lights still on. Then we stopped and went a few more times.
