Rooms in one or more hotels - of the same or different categories - are available as a block up to an agreed date. The participants can book individually online from this contingent via a link created for your event - alternatively via fax form. The quota is a call quota that can be called up up to 4 - 6 weeks before the event. Thereafter, the unsold rooms go back to the free sale, so that you as the organizer do not accept any guarantee or cancellation fees, these are the responsibility of the individual traveler. All bookings after the quota has expired can of course still be requested individually via our booking office after the deadline has expired.
