Tickets must not be misused, copied, or altered. Coupons/purchase confirmations must not be copied or forwarded. One ticket is valid only for the first entry to the event/performance, which means that only the first accepted ticket with its identification is valid. All subsequent tickets with the same identification are automatically invalid. By using an authorized ticket, the Customer accepts the General Terms and Conditions of the Event Organizer and the rules of the institution where the event is held.
