game this friday, any advice?

This friday there is a 12 person tournament home game. The host wants to do 3 tables of 4. There will be unlimited rebuys for the first 2.5 hours, usually a 4-4.5 hour game.
Nearly all of the players are fishy and will look for race situations. My plan is to wait around for the field to thin and then make my moves. With this many people/rebuys it almost becomes a crap shoot. I have beaten this game consistently and can outplay most.

What would you suggest for strategy, thanks in advance
