Hello!
I'm having trouble trying to find a way to nicely ask guests to not bring anyone else. We have these close family friends who have 4 children and 9 grandchildren. Every time we have a party or something and invite just the couple, they always end up bringing many of their kids or grandchildren. At my cousins wedding theyre invitations specifically stated just the 2 names and they still brought 5 guests. How can I politely yet firmly aks them to come alone?
