Polite way to say no kids

Invite only the parents..no 'and family :

Hi Kerri. Could you have the number included on the RSVP with only the "yes" or "no" needing to be checked?

You address the envelopes only to Mr and Mrs X., you can also put something life, "Adults only cocktail hour and reception to follow" on your invites. We put it on our faq page just in case no one understood we don't want kids at the wedding.

Seems to be normal you just say "no children at the wedding" or "adult only". But as PPs have said, you can put the number of seats reserved on your RSVPs so that they know they are the only ones you can accommodate and address just to their names, no "and family". And if anyone asks, tell then that you cannot accommodate to have children

I put this on the FAQ section of my Wedding Website:

2. Are children allowed? This is an adult only ceremony/reception. Thank you in advance for your cooperation.

I also plan to do what CK said on my RSVP, "we have reserved ____ seats in your honor". Which I will fill in the # of guests.

I wouldn't put anywhere it's an adult only reception, since it's not. Just invite who you want there and leave off children.

What PP said, only put the invited people on the invitation, and if you feel it's necessary, the # invited in the __ seats reserved part.

Please don't put anything about adults only on your invite. Not only is it considered rude, it's also not true since there will be three babies and the 14-year-old.

Our RSVP card will say "___ seats have been reserved for ________." I will fill in the number of seats and the first names of the people we are inviting. It's a bit more work, but it makes very clear who is actually invited.

You can be very specific when addressing invites and save the dates--list just the couples' name, and no "and family." When it comes time to make the RSVPs, you can always list:

__ of __ Will attend (you fill in the number in the second blank)

__ of __ Wll not attend

So that they know exactly how many people are invited. This is what my fiance and I are planning on doing. We're only inviting the children in our families.

I'm utilizing the WW RSVP system, so people can only RSVP if their name is on the list. In the invites, there will be an extra card asking them to RSVP on the website and I will have the "There are ___ seats reserved in your honor". I have also added to the FAQ something like "if you wish to bring someone, we request that you ask us in advance to see if we can provide them a seat", basically saying: if ____ isn't on the RSVP list, then they aren't invited....

This was a touchy subject when we were planning because I have a lot of friends that are parents, and I don't want them to get offended by a no-kid wedding. We honestly just don't have the space or the budget to accommodate 20 more people (which is a 35% increase of what we already have invited).

I definitely recommend what others have been saying: indicate how many people on the response card/extra card (if you're doing paperless RSVPs), don't say Adults Only anywhere on the invitation (edit: I have read that this is not proper etiquette and comes across as rude), and only address the invites to the parents, not "and Family".

1. Save the dates addressed to just adults and mailed 10 months before the wedding. (One couple couldn't possibly manage to find a babysitter, in 10 months. Oh well...)

2. Wedding website address on the save the dates

3. 1st page of wedding website had the statement "Our ceremony and reception have been planned for adults 21 and over."

4. Belly bands on invitations had the invited adults names on them.

5. Did online RSVPs, through our website; we had to input the names of those who were invited, so the system wouldn't allow added guests.

One couple boycotted and didn't even RSVP - my uncle and his wife. They're distant/estranged anyway, so writing them out of our lives was effortless.
