Non-smoking areas in caravan parks

Just read with great interest the topic on non smoking areas in caravan parks.
My husband and I totaly agree that non smoking areas would be very much appreciated. As RVers we love the outdoors and, as many people do, we spend much time sitting outside relaxing at caravan parks. The last thing you want is to smell next door's smoke wafting around your area. We hate it. It will make us go and sit inside the van, which is not fair when smokers contaminate your air space. All parks should have non smoking and it should be clearly stated on their websites. With caravan parks always saying that they struggle to make ends meet, anything that would make them a better place to stay would get a big tick from us and I am sure many other RVers.
