The Laugh Floor has nothing more than the main stage. It may have various shows like Crush, but to me a main attraction (which Crush is not), it needs more to it than just a single focal point.
Ok, thanks for making that clear. Now I know what yout saying. I can see where you'd think that from concept art and word of mouth, but once you get there it works better in real life then on paper. It has about five focal points that you focus on from time to time during the show...
-First of all, the stage, as mentioned, is the main draw for the show. But throughout the show you're drawn to these other features...
-the large theatre screen. This is the other main focus point, and is where the crowd views the audience members, and where Roz appears.
-the door screen. On the other side of the stage is a door that Mike mostly uses. (It can be used for other monsters though.) This creates an intersting interplay between Mike in the door, and Roz on the screen. Creating the back and fourth comments that made Mike and Roz so funny in the movie.
-the Laugh canister. This serves to introduce the show's concept in the begining, and also acts as backgrond action, as you can see it fill up every so often. It also wraps up the show as it releases fog and lights up diffrent colors at the top. It "closes" the show with a nice effect and the great look of fog rising into the rafters.
-Another focal point that is understated, but serves a big purpose, are the "eye stalk"-style lamps on the seat backs. They help to give a roomy glow to the crowd, and the theatre. They also create the look of a comedy club, without you even looking directly at them. And they do draw your attention when they start blinking when the power increases when people are laughing, and helps the crowd get the fact that they're laughter is doing something.
-While I won't mention this as a focal point, I will say there are details in the theatre. Like the Monsters Inc. eye logo hidden in the walls, and on the seats, and banners hanging over a large "Scream Floor Testing Area" sign in the back of the room. All of these you have to look for, but help create the feeling of a real place, and help set up the Comedy Club feel.
I was thinking about this same thing when I saw my second preview. I sat in the back, and watched the crowd. They seemed to keep up with the diffrent focal points pretty well. It changes from show to show though. I still see people in Philharmagic not notice Donald at the back of the theatre.
