five - hope to - go camping in Devon.. but where??

[laa]

I'm hoping to go camping with DH, DS(4), DD(2) and DD (5wks) in July. I've never been to Devon but want nice, sandy beaches and a campsite which isn't full of static homes, bars and entertainments. Something in a pretty setting. Any recommendations?

Northmorte has been recommended on here before, laa - by someone with a new baby too IIRC.
