Tickets that are sent by post may be replaced in case of theft or loss. This is done at the cash counter. Duplicate tickets are only reprinted once. We can only deliver the same to the original purchaser against the production of his or her identity card.
In order to ensure that the tickets are not used by third parties, it is best to make them invalid. For this, please contact us (again) one week before the event.
If you have made a reservation or registration specifying details of a closed email account (or which has closed in the meantime), or of a wrong email address, then it is obvious that your e-tickets cannot be delivered.
