Best bet is to play anything and everything that catches your fancy. Like Jim said, staying up late can give you free reign on the A-List games a little bit after midnight! CAX is one of the best shows in CA so the first thing you should do when you get there is to HAVE FUN! (Don't forget to look behind you too, to see if anyone is waiting to play. Especially if they are wearing plaid pants... )

I also like to listen to music when playing at expos to neutralize all the distractions.

That Whirlwind with the industrial blower is absolutely nuts! Too bad the guy playing in front of me had terrible B.O. (It still lingered after he was done playing... )
