Hints for Planning a Network Gaming Marathon?

Malfaetor asks: "Some friends and I are tentatively planning a public Network Gaming Marathon (LAN Party, except for an entire weekend) later this year, starting on a Friday night and ending the following Sunday afternoon. We've already acquired a file server and game servers, as well as did some testing on bandwidth usage of various games. We've also queried local hotels for available conference rooms, and thought about power consumption requirements, and so forth. I ask this of my fellow Slashdot readers: If you have ever hosted or attended a LAN party before, even if it was not of this scale, would you have any input (or horror stories!) that could help to ensure we have not overlooked anything? Any information you could provide would be greatly appreciated!"

"We have prior experience with private weekend-long gaming parties (with 20-30 people) a handful of times per year at the homes of attendees, and usually they conclude with few problems. However, we are planning on this session being bigger and more public, hopefully upwards of 120 seats. Although we have experience with smaller gatherings, we generally know all attendees, and have little experience with larger, public gaming marathons.

What did you do for advertising? Is it more effective to reach the intended audience by advertising on the radio, TV, internet, or billboard? What can you do about the rare, unmanageable, lunatic gamer? How have you handled cheaters (aimbots, wall-hackers, etc.)? Have you brought in sponsors to help offset the cost? Has there been technical support for the non-tech savvy? If so, was it free, or included in the admission cost? There are other questions, but I'll stop there.".
