Here I would not recommend anyone to park for each guest other rules of the game apply entirely to your mood and the changes hourly. A place is not larger than 30 m2 some guests could not open the tailgate of the bus so close are the cars.
The WC / showers are not enough for so many guests and are gladly shared by the hiking and cycling route.
From 12 o'clock there is no warm water to wash off.
A lot of permanent campers are at the front line and lock their empire with their band, so a water access is not secured or very cumbersome.
