We had no kids at our wedding, and I don't regret it - of course, we got married almost exactly seven years ago, which meant that I think only one couple we invited had children. I recall that couple gleefully telling us later on that our wedding was the first time they'd gone away for a weekend without their son, and how great it was to sleep in the next day.

Had there been any small children in our immediate family or in the families of our close friends, I think we probably would have made a different decision, but it wasn't an issue because there weren't really any children to invite.
