Dealing with a poor schedule

So....I just learned I have a local game showcase that I need to go to on Sunday during the Jam. This, on top of the fact that I'll be responsible for the first day of organizing our local real-world meeting. Needless to say, I'm not looking forward to a more-time-constrained-than-usual schedule.

Question to all of you: how do you deal with interventions in the middle of a game jam? I do plan on going by Jam rules this time (as I usually do), so working in a team is a potential option.
