Blizzard has posted a
Survival Guide for BlizzCon.
There was one thing missing from the guide, though.
As a veteran of fan conventions (albeit of the anime variety), I am acutely aware of how crowded these affairs can become. When large numbers of people convene in an enclosed space, not only do we get long lines, but we also get more unpleasantness, namely -- smelly people who are too excited about seeing everything at the con to shower each day.
Showering and using deodorant seems like common sense, right? Sometimes, unfortunately, enthusiasm can get in the way of common sense.
If you're going to BlizzCon, or any other convention, save your friends from public humiliation. If you sense the air around them becoming a little ripe, issue them a gentle reminder. The other attendees will show their thanks by not ridiculing you and your friends.
