My Fi and I have chosen to have an adults only wedding. I know that typically you would just address the invitation to the parents only and that should be enough without having to say it's adults only, but what about a mostly out of town guest list? All of my family will be coming from out of town and many of them have kids and I know that if the children can't come at all many of them will not be able to come. Because of this we are providing childcare at the venue. How can I let people know that their children will not be allowed in the ceremony or reception (same location) without it coming off as rude?
