I would be up for it next year i should imagine, but would prefer a change of venue. There was nothing wrong with where we were-far from it, but its always good to explore new places. It was also a long way up north (for us londoners anyway). Think perhaps the peak district could be an idea? Not quite so far oop north, and i'm sure there are hills there. Weather might be a bit nicer too :-)
In terms of dates, i can't plan a week ahead let alone a year. I think its going to be better sorted nearer the time.
