No. You need one Hotelcard per room, i.e. for a double room or even a multi-person room/family room you only need one Hotelcard. The prices listed on our portal always apply per room and night.
Conversely, if you would like to book two rooms, you must also present two Hotelcards or two Hotelcard holders must each be able to present one card.
Please also note that the Hotelcard is personal, is in your name and is therefore not transferable. You must present the Hotelcard in physical or digital form together with your ID at check-in in order to benefit from the Hotelcard discount.
