No kids

You are right that not everyone will see it on your website. One popular idea that many on here do is to put on the RSVP card "We have reserved X seats in your honor." That way it is hopefully clear who is (and isn't) invited.

If people don’t pay attention to the envelopes and rsvp with kids anyway, you get on the phone immediately to let them know.

That is a huge amount of kids! I would include that info everywhere you can!- on a details insert with your invitation, on the RSVP card, on the envelope, on your website

View Quoted Comment I think I will order detail cards

Here is a list of areas you can tell guests it's adult only

1) Put "Adult (18+) Reception to follow" on your invitation

2) Address Envelopes Accordingly

3) "We have reserved X seats in your honor/ or _ of X Seats"

4) Add it to your Wedding Website

5) Do online RSVPs where only the adult names will show up on the list

If people still try to RSVP their kids, then call them as soon as you get the RSVP. At this point though they are not accepting the no kids and are trying to swindle you

We had a no kids reception as well. We told everyone but we also put “Adult Only Wedding/Reception “ on the RSVP cards.

I know it’s not strictly traditional, but if you know your crowd and have a feeling they aren’t aware that only those on the invitation are actually invited, you may want to note it somewhere.
I know, it flys in the face of invitation protocol but you know your circle best, and if this is a concern, they are already not following the “rules.”

On your RSVPS you could add a line that says “____ of seats reserved in your honor” and then fill in the number for them. If they add kids then politely call them and tell them due to limited space we cannot have kids attending

I would add an insert letting guests know!

I agree with all of this!

We don't have RSVP cards, but when they go to RSVP online, only those names of who's invited will pop up, and it doesn't give your guests an option to add someone in. I also agree that if someone tries to write their kids names in, immediately contact them and politely tell them that children are NOT invited.

We're doing the same and the RSVPs will have a line saying "____ of # Adults Attending" and our details card has a line saying that only the children of the wedding party are invited (and they're literally only invited for the ceremony since they're in it and will be leaving after dinner at the very latest).

I hear you we have 46 kids 😅 out of 150 guests! Literally a third of our guest list is just kids. It's crazy, I would have liked kid free but my family was NOT having it.
