We did not skip TSMM during the TOTP. In fact, we figured the line would be shorter at night during the party than during the day because not as many people were in the park at that time. In any case, the line was no longer than it is for any other popular ride. It was nothing out of the ordinary. And actually, seeing that it is a brand new ride which is extremely popular, I think the line is pretty decent compared to what I expected it to be. (I remember when Star Tours first opened in 1987, and the line was all the way down Main Street - now THAT is a long line!) It was about 25 minutes or so, and it moves fast. When I think "long line," I think Nemo or Indiana Jones or Splash Mountain. This TSMM line - on our TOTP night, which was October 3 - was nothing that intimidating. And the TOTP was very crowded in other areas, so we felt we could slip away and get onto TSMM while people were doing other things in DCA. I think it all depends on what you consider a long line to be, and what you are willing to stand in line for. We have waited longer than that to get on the Storybookland Canal Boats before, so this seemed fine to us! And it is worth it to us because we love the ride!
