Just in case you haven't followed other CP threads, the show is 45 min, but the total time needed to watch it is much, much longer. If you don't have a CP dinner pkg, you'll need to line up at least an hour before the show you want to see and maybe longer depending on the narrator. AND you may not make it into the show. Reports from yesterday's first CP is there are only a few rows (maybe 100 seats) for guests without the dining package. So if you're in the standby line for the 5:00 show and the standby seats fill up, you'll have to wait through that show to see if you can get into the next one.
You can hear the show and see some of it from the walkway behind the theater or the outside tables just across the way at Liberty Inn. That's becoming a pretty well known "secret" so you may have to stake your claim on one of the tables pretty early as well.
