Camping at Airshows

I am thinking of taking my nipper to an airshow combined with a fun overnight camp.

Are there any forum readers who can offer serious(ish!) advice on stuff like the best shows to go to with camping grounds nearby, other things for kids to do nearby (if they get a bit bored with planes – and that’s ok with me, don’t want to ram it down throat )

By the way, I don’t mind paying my way to a show to help pay for the event – not into gettting something for nowt….
