The event is full...I say for those we need to teach (there are only 3 players who are non-members, right?), we give them the 5 minute version and then let them play in a whole game.
Perhaps while we are doing ice prep, someone can go over some things with them briefly. If there are 3 people, we can give them quick one-on-one tutorials right before they start.
I say we just integrate new players into the games. That's the best way to learn. We'll keep instructing as we go along. Everyone will teach.
All of us want to curl at these events. If they are full, it shouldn't be a problem to do that. We don't have the ice space for a whole sheet of teaching anyways!
