If you want to plan a meet-up, there are 'lunch hours' that have no events scheduled. You could plan to meet, say, at half past noon in the middle of the quad on Saturday or Sunday, at the campfire or dance Saturday night, or maybe all pick a certain slide show or talk to attend.
And I know it feels a bit geeky to wear name tags, but it's a great way to spot folks you know but don't recognize at first!
