Lyndon Top is My favorite place to park, away from the other regimented sites and if you want to you can visit the Golf Club bar as a guest. just quiet and not expensive at all .I'm going to go against the majority view here.
The CC model is one I hate. I think Lyndon Top is the ideal model and Shell Island isn't far behind.
Grass, no marked out pitches - go where you like, however you like, as long as you aren't too close to anyone else, water, black waste points and that's about it. I suppose a drive over grey drain would be nice but not essential.
