We are definitely having an adults-only wedding, and the people most important to us who have kids have already been informed. We still have 9 months until the wedding, so we haven't sent out save-the-dates or put up our wedding website. But I'm feeling kind of paranoid that even if we mention that the wedding is adults-only on the website, save-the-dates, invitations, AND address the envelopes specifically, people will just skim everything and/or not get the message and bring their kids anyway. Has this happened to anyone? How can I best avoid this?
Also, any tips on the most tactful yet clear way to phrase that the wedding is adults-only on the invites, website, etc.? It's not due to size or venue limitations (which would never work as an excuse, since our venue is quite large). We just dont want kids at the wedding.
