Help! No children @ wedding

You can specify No Children at the wedding, that decision is completely up to you. Just do what PPs have suggested, stating how many seats are reserved on the RSVP, and making a note of it on your wedding website.

You cannot tell your guests that they cannot bring their children with them to Hawaii. That's their decision.

When you have an expensive destination wedding, you are basically asking your guests to give up whatever their vacation plans were for the year, and go where you want them to go instead. As Samantha said upthread, they may want to extend their stay and make a longer vacation out of it, since they are there anyway.

I'd suggest just saying No Children, and be done with it, with no excuses attached. Suggesting that it will be more affordable for guests to not bring their children is opening the door for them to say that it's ok because they'll be staying over for another week with them anyway. As others say on WW all the time, "No" is a complete sentence!

I think this is the best suggestion! Taking the time to call the couples will probably be the clearest form of communication. Thanks!

This is a great idea as well! Thank you!

No, we want to have our actual wedding in Hawaii. FH and I were completely ok with guests with children declining, there are very few. I've spoken to all the couples and they're ok with leaving the children with their grandparents.

This is definitely what we're going to do!
