Brisbane Fine Wine Festiva Trip

My sister's boy friend is going to Fine Wine Festival held at Brisbane, Australia on 06 to 08 July 2007. We are so envy where he can take part of the event and he has chance to taste over 600 wines there. He is going with his colleagues in group of 4 person. They had already booked cheap hotels in Brisbane. Of course the Brisbane hotels cost will be bare by their boss. How much a boss will going to spend for these 4 persons on the 4 days 3 nights trip? That's the reason why the boss prefer cheap hotels in Brisbane. :P
