$1000 NL Holdem WSOP Event

I'm giving in and playing in my first WSOP event, the cheapest NLHE ovent offered. It starts tomorrow (Monday) at noon, and is supposed to run three days. The most expensive tournaments I've played in the past cost $540, so this is a bit of a stretch for me. Also, I expect there'll be over 2000 entrants, and I'll probably be playing 11 hours tomorrow.
