Where to camp?

There are so many places to camp in the uk, how do you choose? Do you want the all singing all dancing ones with kids galore, pools and club houses? Or something more natural? Back to nature? Something in between? This is a great website for some inspiration http://www.coolcamping.co.uk/
Other ideas I'd love to hear!

Cool Camping have just added cool campsites in France too - very handy as we're planning a camping trip to the Dordoigne this summer!
