Been the once, a good few years ago before it was taken over by Haven. Pitches were situated in woodland, a bit on the crowded side I thought but it was o.k. Clean and no problem with noise or unruly behaviour at that time. If I'm thinking of the same site there was an indoor swimming pool which was fine. I can remember a clubroom which was so dark inside that you could hardly find your way about.
Overall the site was o.k. but I wouldn't rush back. This was approx 10/12 years ago so there has probably been a lot of changes. Good Luck.
