Cheers mate, that's a good idea - I was already thinking of the Saturday night as it saves a rush from work on the Friday or a rush to get home on the Sunday. I'd somehow got the impression that this was some kind of annual event which is why I was asking if it was any good, I must have been getting it mixed up with something else.

I did find this though

Win a meal and free accomodation plus tickets for the event.
