Do all the tickets have to be printed out individually?

To make life easier for you and your guests, we work with a group barcode. You will receive this with your booking. Group barcodes go up to 80 people. For example: are you coming with a group of 120 persons? You will receive two group barcodes: one for 80 people and one for 40 people. This does mean that the group should report to the ticket entrance together and at the same time. Individual visitors then no longer have to show their own barcode.
