We pre-booked and paid in advance in full but made the fateful error of choosing to visit in mid June. As said busy single track tarmac road with also a tight entrance for Caravans. Well oiled arrival routine and talk. Lots of seasonal & rental cabins now, only part Touring. We for sure had been allocated the very worst pitch (the side grass verge at Pot wash / toilet block) on this very very packed site. No privacy, very noisy 7am to 11pm, constant folk taking shortcuts across every way they could etc etc. We left early due to genuine family reasons, sad but somewhat relieved. NB The better family type sites in Switzerland, especially near Lakes etc are extremely popular, but will pack units onto every bit of grass verge they can and therefore do not have to tolerate any whinging.
