Flying to VA

We're leaving tomorrow and the only thing I've assembled are the presents we're taking with us. So tonight I have to deal with the challenge of trying to fit everything we need + Christmas into two carry on bags. Well, technically four. But I don't want to check bags, because it's too expensive, and its easier to not lose stuff if I'm responsible for it. Right? right. So the challenge: What can I live without for 10 days?
