+2 or +4

Further thoughts; for those who stick around at the end of the first session, and who also have formed a couple, I would give the couple 100$ to help pay for the two dates they do and suggest that one of them pays the balance for date #1 and the other pays the balance for date #2.

Once the winning couples have been chosen, I will have someone give them financial advice for things like budgeting, investments, TFSA, RRSP, RESP, Child Tax Benefit, etc.
