Thanks Les.

Tyke - yes, hilarious (yawn).

Arthur - yes, I have read that page. As I pointed out in my OP, it's not essential that I know any of this ahead of time and I didn't want to bug the organisers with trivia. I just hoped to get some friendly advice from those who had been there before.

Still living in hope of that......(with exception of Les' post which was useful, ta!)
