We were touring Portugal in our camper and one night we stayed on a beach all on our own, my Wife said is it safe ,i thought she meant the tide.Anyway we went to bed about 11 pm and was still on our own (marvelouse sunset).Got up about 8am opened the window and was greeted by a German lady in their camper who was about 24 inches away and next to them others the same i could not believe that they had come in so quite in the night ,.As we were moving off later it was only funny at the time.Of course if there had been an incedent like fire etc i should imagine we are talking about
