Hi, I went to Bedgebury last year, the weekend before the August bank hol. It was busy but not heaving - we were in Apple field (which is for families) but they had just opened up another field as it was getting a bit cramped - we managed to find ourselves a space in it but the other field looked just as nice, although slightly sloping and not as flat.
The place itself was lovely, v. chilled out and relaxing. Saturday they have local musicians playing in their big tipi and the local pub sets up a bar/kitchen if you don't want to cook - this was lovely and the DCs had a great time running round while we chilled with our wine.
We were only there 2 nights so didn't use the showers (went swimming on the way home) but they looked ok - no basins in the portakabins they were in, though, so teeth-cleaning had to be done in the washing up area or the loos. The loos in the fields are composting, which the DCs declared 'disgusting' and refused to use (they are fine but unlit so take a torch if visiting after dark!) - there are flush loos by the showers but they got very dirty very quickly and ran out of loo paper on Saturday night. Loads of hot water in the washing up areas and big sinks (all in a stable conversion so nice and dry). Also a family bathroom if your children don't do showers.
Nearby is the Bedgebury Pinetum which we loved, a brilliant day out with loads to do.
It's fairly peaceful at night, chatting around campfires, but we didn't see anyone patrolling so I'm not sure what would happen if there was a rowdy group.
We're hoping to go back this year :)
