Hi guys, thanks for all the replies!
Just to wrap the thread up, and to aid anybody else if they are searching for this subject in future:
Stayed at the Beara Farm site in Buckfastleigh. It was like a cheaper, nicer, better equipped version of the Vaynol campsite. Andalot of Netherlanders!
I phoned up the Harford Bridge one... for a 'basic' pitch, for two tents, for one night: £31.82!!!!
