C3 actually had three entrances into the con every morning. If I recall correctly, there was a line on one side of the convention center for fan club people, one on the other side for everyone else, as well as the not-widely-known skywalk entrance from the building across the street. But yeah, even with all that the lines to get in were murder.

GenCon are the people that have handled the last three celebrations (2, 3, & 4) and while they did a much better job than Wizards of the Coast did with C1, they still haven't seemed to get it right. I remember them having to shut down the store at C3 on Saturday because there were too many people in line. The people who only had badges for that day went ballistic but all GenCon did was tell them to come back the next day. I'm sure that's a big reason why this time the store is running 24 hours a day. I just hope the rest of the con goes smoothly. From what I hear from someone in the know, there are a lot of cool things planned, but nothing is concrete yet. Apparently LA is much slower at planning things than Indy was.
