Ah sorry just read your post again, yes we also find them with no one about, but just park up anyway. This is the back of our very first one, stayed there 2 days , never saw a soul.The year we joined it we didn't stay at any first full second no one there to ask third couldn't find it!!! So we discovered Aires and asked at tourist information most have a sheet for the local area. We've stayed on a few passion vineyards since never been asked for membership.
