The teams are very busy on Saturday, so don't expect them to be able to spend time talking. Some will be able to spare a few minutes but that's about it. Once they are done with turn ins, at 2:00, they may be more likely to talk, but they'll also be cleaning up.
There should be samples and demonstrations going on from the folks putting on the competition, but the teams aren't allowed to give out food based on Sam's Club rules.
The awards ceremony is typically at 5pm.
