We are looking for a campsite that won't cost us over about £15 p/n in the Lincolnshire area. Don't anyone say look on UKCampsite, I've looked and looked and looked and it's doing my head in

It is for 2 adults and a dog, must have showers and toilet, but not bothered about entertainment as such, as long as there is a shop and maybe a pub within easy walking distance.
We are attending the Summer Camp and would like somewhere to travel on to for a few days before continuing home to Lancs. So anywhere north of there if you can recommend a site would be great if not Lincolnshire.
I would be grateful for anyone's personal recommendation.
