Tickets are not refundable but may be exchanged for credit of the base price (excluding fees) toward a future performance. Notify the Box Office of your intention to exchange tickets at least 24 hours prior to the performance. Tickets returned with less than 24 hours notice prior to the performance may be donated back to Landmark as a tax deduction. You will receive a letter acknowledging your donation. Credits must also be redeemed within the next season after the original ticket date. Programs are subject to cancellation or change. If a program is canceled, ticket price will be refunded.
