With my fiancee and I, we only have 3 children at and in our wedding. We are specifying that this is an adult affair only. To me, if you tell people adult reception they will probably bring their children to the ceremony and then either leave and go home or leave and take them home and have to come back and 9 times out of 10 they won't come back. That's why we are choosing to say adult affair only. Just our opinion.
