Funnest thing to do is just eat dinner in the Gaslamp after Comic Con gest out and people watch. The zomibe walk is hysterical at the beginning of Comic Con and then Saturday night is just out and out weird. Didn't go this year but apparently Hall H was a fun stampede when the guy got stabbed near the eye with a pen.
I do have to admit that I'm insanely jealous of the swag that a few people got at some of the booths.
