I'd like some suggestions please as I can't find any search criteria to help me. I'm looking for campsites that are on the same site as a family day out type attraction within say three hours drive of Oxford that would keep my family amused for a weekend or a few days. The kids are turning 10 and 8 this summer. It could be a country park / theme park / farm park / stately home / activity centre etc. where campers get free / reduced entry / extended open hours or some other perk. We've been to Wellington Country Park in Berks which was great for a one-nighter and are contemplating the Hop Farm in Kent but open to suggestions.
Hatton Country World / Farm Park near Warwick do camping in the summer holidays, lots of nice places to visit around that area. Or Midbrooks, Near Trowbridge is a more basic site but has animals, where you can help around feeding time, you can hire bikes cheaply on site and have real campfires. Have also look at Far Peak Camping in the cotswold - looks good for slightly older kids - they have climbing low ropes etc.
------------- 2015 sites booked so far: Cotswold Farm Park, Ninham IOW, still some more to book
Cotswold Farm Park is well worth a visit. I believe that if you are camping there you only pay once, and your entry ticket is valid for the whole of your stay. In addition lots of the rare breeds are in the field right alongside the campsite - - we enjoyed it.
