I would definitely raise more pre-flop with a hand like QQ in this situation. I actually play some late night tourneys on UB myself and all I can say is these players are LOOSE. I dont know if they just came back from the bar or they are half asleep or what but if u just wait for big hands and then push hard they will still pay you off. QQ wants to be heads up on the flop. Raise as much as you think you can get away with while still getting 1-2 callers.
