I think the Date Nights are still important. No matter how long you are married, always make time to "date" and just spend time together!
Well, I'm not married so it seems like I would skew your results ... However, AWESOME poll! How fun! And, I think that the thing I would find most "bonding" when I do get married is probably the "talking late into the night" one, because that's the one that feels most bonding to me now.
I picked one...but all of these play an important part in a happy marriage. Try to find a balance between them.
