We have been stuck on quite a few rides. The most terrifying was Rock n Rollercoaster (dec. '07). The ride started fine and then kept slowing during turns and thru the corkscrew. We had just come out of the loops when it slowed to a crawl and just stopped. It was very claustrophobic being in the dark & locked into the seats. It lasted for about 10 minutes. Didn't go back on for the rest of the trip.
This one is fun and scary!
Last December we were on a Hidden Mickey hunt with Steve Barrett (author of HM) and were checking out the hidden mickeys on Pirates when all of a sudden the announcement comes on that they are experiencing technical problems and to stay seated. My DS freaked out as we slowed and stopped. Turns out, as he told me, he caused it to stop. Yeah right, I answered. He said he quietly said something, and after he did, the announcement came on. Still not believing what he was saying, I asked him what he said. He wouldn't tell me for over 5 min. finally he said, "well I said, "George isn't real" and just as he told me what he said, the ride lights all came on! No kidding. The entire room was lit with the bright after hour lights. We sat there stunned as he told me the backstory about George the ghost who supposedly haunts Pirates in a fun way by stopping the ride if you say you don't believe in him or that he isn't real! We were stuck on that ride for over 40 minutes. It wasn't until we got off and told some people about what happened that we learned more about the story and that DS should have apoligized to George, and that would have started the ride up quicker. I wouldn't have believed so much if I didn't experience it with him! Ooooooo
