A group counts as 12 paying persons with reservation in advance and payment by one person. For the same period of validity, every thirteenth person is free. The group rates can be found here.
Please use a group for all persons who use the same offer with the same duration. In case of discrepancies (different persons use different offers, different arrival and departure days) a new group can be created with the button "Plus another group". After completing the form, an offer will be sent by e-mail.
