As stated in our general terms and conditions, we do not take back tickets that have been sold. For a small additional fee per ticket you can take out cancellation insurance for your entire reservation. If you are faced with a setback just before the event and are unable to attend, this insurance will refund your tickets. In such a case, contact the insurer directly and be sure to give them your reservation number. For the reimbursement, the insurer will ask you to provide all relevant evidence or documents.
