That brings back memories! - we had the same setup at Queen's college (a residential college) at Melbourne Uni. We had about 200-250 players. As someone else said earlier: "One of the most stressful months of my life!". One game (we played once a year) I made it through to the last two players left alive, both of us gunning for each other. By that time everyone knew who we were so it was doubly difficult to perform the deed un-witnessed :-)

Good times!
