Event idea:
Dating week!
Everyone is assigned 1-3 partners which they have to hang out with for an hour or two out one-on-one on times that suit them both over the course of one week.
Event ends on sunday with everyone telling the highlights of the week.

Alternatively; speed dating but only with one person, for 1-2 hours. People are assigned to each other and then go hang out independently in their own instances.

Thoughts?
