Yeah - sausage fest is right, and Mario - you are so on the money about the JT playing tops. Made me laugh. It's mainly the Germans and Belgians in my experience.
Rosie, don't waste your time going sweetheart, you'll be covered in drool after the first hour, and thats not attractive.
I normally organise a VIP nightclub soire instead of going to the official party. You should do that sort of thing instead. That way you get to invite the people you actually want to hang out with, and poach all the chicks that would have gone there by promising champagne and a fully stocked hotel suite for some after-hours fun and games. It's always a lot more exciting.
