All of this discussion is based on using two fields for camping plus the Recreational Field for the dance venue, not three for camping as I had assumed originally.

So there is the third field - if it is in the same ownership and if it is available it could simply be added (if the festival could afford it) - and that would much increase the capacity for camping.

It really is a very nice flat field........and the sheep are friendly too.

If minibuses need to turn around and go back the way they came, my guess is using the entrance to the Observatory. Looks ideal......
