If you can't stay through all of Act II, I suggest you stand in the back for Act II. To make a bus at port authority, you'd have to leave the theater by 10:30 at the latest. A lot happens in those last 15 minutes and you are thinking about sitting up front?
Do you really want the entire theater watching you get up and leave as the show is reaching a climax? Why not bring a tuna sandwhich wrapped in plastic to eat through act I and make a full night of it.
If the audience could do better, they'd be up here on stage and I'd be out there watching them. - Ethel Merman
