Voucher
The voucher can be redeemed for all events whose ticket sales are handled by the Radialsystem. Redemption is possible online as well as at the daytime and evening box office when purchasing an admission ticket. The voucher itself does not constitute an admission ticket.
Any remaining balance will be retained and may be used for future ticket purchases; cash redemption is excluded.
