What else can I do at poker tournament events?

[stackflare]

I'm thinking of participating any tournament events like Pokerstars APPT, WSOP, WPT, etc once I have the chance to be there. What I'm wondering about is whether there's any interesting things from those hosts so that I can do something even though I'm out of the tournament early. Of course it's possible for me to play some live cash games, but I'd really like to know what I can do there except just playing some games.

You guys' kind replies to this wonder would be greatly appreciated.
