The Weardale in is home to the Mad Axeman Rally for the last couple of years, good meet up point and not far from decent roads, Hartside cafe, Hawes, Sedbergh, Devils, Durham etc... Perhaps give them a bell and ask for a deal like Squires, ie: we eat and drink at your place/we camp for free?...I cant do anything untill Monday but would be happy to oblige in helping out with owt'.
So there's that one to bear in mind.
But could also be worth considering the Tan Hill Inn. I know it's a long way from Lindisfarne...42 miles from Newcastle. But there's free camping & use of the pub. We've had bm events there before and sometimes there's a band on. last Saturday there was a band which had original members of 'Lindisfarne' in the line up, interestingly enough. It was also full of Geordies lol....you also get free entertainment from the the whacky and rather unique pub staff
You could organise a ride out via Middleton in Teesdale / High force and then on up to the gorgeous Northumberland coast
Just a suggestion.....
