Carlos,
I don't know how I missed this but it's an excellent series.
I only ever went on 2 caravanning holidays with my parents and hated both. There's something intrinsically wrong (IMO) about cramming whole families into a small metal box and expecting it to be an enjoyable and entertaining experience. Give me a solo tent anytime.....
I suspect that the laws are strict - but not specifically for holidaymakers - but primarily to avoid so-called "Travellers" from pitching up and creating a long-term / semi-permanent encampment wherever and whenever they choose. This time of year, we sometimes get some taking over an open space near to where I live and, by the time they've been evicted, the place is a total mess and costs a fortune to clean up.
