When I saw the Nemo show Thanksgiving weekend, they had people exit to the right hand side exit (right side if standing looking at the stage.) We sat over on the left side and it took us a long time to exit. In fact, as we got outside (we were one of the last ones to exit the theater), the new crowd was being let inside. We could have hopped right in line with the people moving foward towards the theater, because we had to walk through them in line to exit.
As for any disappointment in the show, my only disappointment was the high wire part, I felt they could have done more. The rest of the show was very cute!
