I can't tell from the response if he grasps the magnitude of the problem at hand here. Guiding people to the right place and having a few people try and ask people to slow down doesn't change the fundamental problem at hand: Thousands of people have a huge incentive to "get in first" in order to claim seating. This isn't something that can and should be fixed by "hey guys, don't run". A queue line for each division that lets people inside in an ordered fashion would do it. Probably takes the same number of extra people as other methods. You could gradually bring the lines in, let in 20 at a time every 30 seconds or so from each line, etc.
