Unless otherwise agreed, for groups of twelve persons or more a payment of 10 percent of the total booking price shall be due immediately on confirmation of the booking. Unless otherwise agreed, the remaining amount will be due no later than four weeks prior to arrival without the Hotel issuing a separate payment reminder. In the case of group bookings booked less than eight weeks prior to arrival, the first advance payment of 10 percent shall not apply and the total booking price will be due in full in advance immediately on confirmation of the booking.
