When I was about 8 years old, my mom and I had gone with my sister to Catholic schools day at DL. We had a great time as big sis went off with her friends and mom and I hung out together, but we got stuck for what seemed like forever on POC. It was at the part where the ship is bombing the town and vice versa. Bam, splash, bam, splash.............. Everytime for years after that, I would hold my breath at that part hoping we would not get stuck. The cool thing was, that eventually our boat was rerouted out a side exit and we walked through the backstage area back to the front of the line and started our ride over. It was neat seeing behind the scenes even for an 8 year old. Some day as a grown up I'm going to take mom to WDW and go on the tour of the MK.
Also got stuck last June on JIYM, twice in fact. The first time, the cars stopped for a couple of moments and the sound stopped. Then the cars started going but no sound. Finished the ride with nothing happening but the lights were down. Decided to try again later but as we were riding along, the cars stopped for a moment again. DD says, oh this is not a good thing! Sure enough, the ride started up again and all seemed normal, but in the next area, stopped again. Sat there for several minutes, all the lights came up and eventually a group of CMs came and sort of caravanned everyone out of there.
