Open Rehearsal ushers will not be checking ID, but reservation in advance is required. Groups or individuals not appearing on the reservation list on rehearsal day will not be admitted to the auditorium. Only adults who are accompanying students will be admitted to Open Rehearsals, such as in the case of teachers, parents and chaperones. Attendance of children below middle school age is discouraged. Every attendee, regardless of age, must be included in your total ticket count.
