We were on Splash Mtn and the ride stopped when we were about 3 logs before the drop for the Laughin' Place. The music stopped, the lights came on, and we were told that a CM would come to assist us to get out of the logs. Several CMs arrived within a couple of minutes, released the restraint bars, and had us get out of the log one at a time and line up along the wall. When everyone that was in sight was out of the logs, we walked single file to an exit, and down an emergency staircase into the back of Magic Kingdom. There were old parade floats, and old SM logs (it was pretty cool to see, I must say). As we walked through the "door" to get back into the park, a CM gave us a paper FP that could be used on any ride (except 7dmt). No one ever mentioned what the problem was, or why we were being evacuated. Now everytime we ride SM, when we get to that section of the ride, my kids (and me) all announce, "this is where we got stuck and had to walk down". It was annoying at the time, but made for a great memory.
