Just an idea - how about the weekend of 19th - 21st June?? No school holidays, weather may be more clement (although no promises as this is Cumbria) and I have an idea that it may be quite a significant date for some strange reason?????
That weekend sounds pretty good actually (it's the one weekend in summer when the Avebury Megameet would probably not take place). Info on B&Bs up your way would be great. I can post some details of local B&Bs if you want and we can take if from there?
Let me know what you think
