Was in MK on 15OCT12, and was lucky enough to ride Under the Sea twice during "dress rehearsals". The first time was around 1400hrs. The ride still has it's bugs. We were stuck in front of Ursula for almost ten minutes. When we exited the ride, we noticed that the CMs were preventing any else from entering the queue. Our second ride occurred around 1920hrs. This time we got stuck for five minutes and when we finally did get moving, there was no audio. I am not complaining. In fact, I feel very fortunate for getting the chance to ride it.
