Some really great advice so far.
Play my game.
Stay patient/don't rush.
Don't get too fancy; there are plenty of people who will just gift chips.
Eat/sleep well, get some exercise.
Get away on dinner breaks.
Bring a sweater.
Turn off or ignore your phone.
Look to exploit really tight players/end of day play.
Get good table draw/cards.
I'm really looking forward to this, I've got some snacks (granola and trail mix, stuff like that), I'll have my iPod filled and always have a sweatshirt, my medication, and other necessary little things with me (I often bring a backpack when I play).
I'm also planning to start staying up late the week before I go to help with the three hour time shift, so I don't wear down too much near the end of the days. I don't drink much and have to regulate my sleep consistently anyway, so that shouldn't be too much of a problem.
I've got 30% of my own action and am just excited to play. I think the recent development of my cash game will really help, and my generally patient with spots of aggression tournament game fits in really well with deep stacked tournaments, which have always been my favorite.
Any more advice, I'd love to hear it. Just stuff that an ME noob might not know/consider.
