Multi-table tournament tips

I am attending a multi-table tournament this weekend at my college. I am mainly a single table tournament player, and am use to playing very tight. I am not sure if thats going to work with 20+ people. Mind you, these people I am playing with are not extrodinary, but there are a few good players. Basically I am use to playing Pocket pairs, and high suited connecters. I am really not sure i am going to play in a multi table tournament, so please, any adive at all would be great.
