Swimming in the Shallows has student rush for ten dollars, one hour before curtain. Students can get tickets in advance for twenty dollars, I think, as well.
I have seen the show 3 times. Two weekday evenings and a Saturday matinee. Never has the house been more than 2/3 full. You shouldn't have trouble getting a seat.
