Ken,
there are lots of B&Bs and hotels, I will post some choices over the next couple of days. I suspect it gets very busy that weekend as there are a lot of folk here for that event, I will do some research.

It is quite practical for doing just one day, I'm not sure if it will go down well if we all only did the one day and no-one was there at all the other day. I will sound them out. There may be a problem with the commitment at such an event. Although every year I have been there have been completely empty areas and I don't know why, it could be that others only do one day.. I will find out.

To establish the size pitch we want I will need anticipated numbers and everyone attending will need to book in advance for insurance purposes.

I will do some research and come back.
