Re: A family day... what do sailors do?
I would like to add, the Home Port or Home Marina can add a lot or distract from the experience. Our marina is more of a yacht club atmosphere with Pool, Hot Tubs, Picnic Areas, and wonderfully Landscaped Grounds.
It is not uncommon to see Families with small children go out for a sail in the morning and be back to spend time pool side in the afternoon. Small children just don't seem to have the attention span to spend 6 - 8 hours on a boat no matter how much you entertain them, but place them poolside or on a beach in the sand and they are happy for hours.
Your location of where you dock/sail can make a difference in the big picture of things.
Make sure there is plenty around you to keep everybody happy, not only the children but also your wife.

If a man is to be obsessed by something, I suppose a boat is as good as anything, perhaps a bit better than most - E.B. White
