After staying at Commons wood recently and now reading the other reviews, I sort of agree with both sides.. Its a great site in a great location with clean refurbished toilet block, still slightly dated looking and could of been lifted / modernised maybe a bit more, but all the same clean and tidy. As for 'commercial' vehicles, did see a bit of this too.. Also saw people that seemed to be almost residents but that left site and returned the following day... Hence not breaking any 21 day rules I guess.. What I felt was more of a problem was a noisy droning rattling noise coming from an American RV air con unit which was all through the night... Or the quite noisy American pick up that the owner had to drive to the toilet block in at 10-30pm and return just before 11pm.... Or the vehicle that used to leave his caravan at 4-30am every morning.... I can only advise of what I see / experienced... I would return to the site but I would consider where I pitched a bit more next time and hopefully not be bothered by these problems again... I would also say... its not just this site, as it seems to be happening a lot more on 'CL's and Club Sites nowadays.... Which is a shame for us that go away as a leisure break....
