I'd definitely suggest trying to find a team ahead of time. The events that I've been to have always had several people without a team but it isn't until the event gets going that people start talking and working together. I think most organizers do not do enough to try to counteract the awkwardness people have when meeting for the first time. It wasn't a hackathon, but I found my current colleagues for a challenge.gov app challenge through twitter search (one guy tweeted seeing if any of his followers knew a specific API and I responded) -- now we are in business together.
