Tips for SDCC 2011

I've never been to SDCC (or California for that matter) and was planning to take a trip with my friends there next year.  None of them have been to the con either.  I was wondering if anyone had advice for us noobs.

i plan on going next year also. i'm gonna go ready buy a bunch of shit and party afterwards. lol

tickets go up on their site today. i plan on going, it'll be my first SDCC
