A whole bunch of us went up there to give it a try.
Be warned: the two main venues are far too small for the number of tickets they sell, so unless you queue for ages you're not guaranteed to get a seat or even to get in at all. The sound was variable.
'Reception' was a nightmare of Heathrow-like proportions - it took us about two hours to get in.
There were singarounds and tune sessions both days. And the concert line ups weren't bad.
Accommodation was pretty good for the money (but then we all got free upgrades from 'silver' to 'gold'). And the weather was pretty good for December.
