Shooting video at Comic-Con

I’m in San Diego for Comic-Con through Sunday capturing video for sci-fi blog io9.com. I’ve never been before, but some say it’s the “Burning Man of comics” with some 100,000 attendees expected. Being a n00b, should I expect to be spanked on the way in? Is there anything that is a can’t miss experience? I’ll update with links to video on io9 as the weekend progresses.
