I can't really add to what has already been said (toilet/showers needs improving and some lighting would be helpful for when it is dark).
It wouldnt be fair to mention the food because the OP only asked for comments on the campsite itself. However I was slightly dissapointed to only get 1 rasher of bacon in my roll. I know it was only £1.50 but one more bit of bacon would have been nice.
However it truly was an excellent campsite because we were all made to feel welcome, we didn't have many (if any) restrictions imposed on us in terms of keeping noise down etc. Heck we were even allowed a huge bonfire..!
And we were allowed to take over the pub in the evening and shelter from the rain
