For 2 nights with a Camper, 2 persons and a dog I paid 82 euros, which was quite expensive. Standing in a circle was not our thing, no privacy. Behind our camper there was also a place rented out for a tent, which I think was not in order at all. To visit Lake Constance you have to pass a terrace (with ticket). With the dog you have to stay on the terrace and you are not allowed to take pictures. Not for me anymore.
