$2,500 Freeroll Tournament - Strategy

[YoungPoker2]

I am playing in the Party $2,500 freeroll in a hour or so, and I was wondering if anybody knows of a general strategy for these kind of tournaments? The only people that are allowed to play in it are people who have registered a new account within the month, so I'm sure most of the 3000 registered players will not be very good. I was wondering if there is some general strategy I should follow for these, aside from weak-aggresive? If this tournament is anything like the ring games with newbies, I am worried about encountering numerous suckouts when I dominate pre-river. Less all-ins? More limps? More/less bluffs? Let me know please.
