Telling people about no plus ones

“We just received your RSVP and we’re so glad you can make it to the wedding! Unfortunately, we’re not able to accommodate any extra guests. We hope that you can still attend, but please let us know if this changes your RSVP.”

View Quoted Comment Exactly this. Polite, to the point, yet still firm.

I agree with pp. that’s the best way to address the situation

Totally agree with pp. it’s very polite but firm. I think it’s rude for people to assume they can bring other people.

Yes, exactly this. And make sure you stick to this with every person, no exceptions, otherwise be prepared for upset guests. This is for those who invited their plus one, not anyone you may have extended this offer to already!

Make sure that you correctly establish what plus ones and social units are. Anyone in an established relationship when you are making your final list and addressing them at 3 months out, is a couple, one social unit, and both people must be invited together, whether or not you know or like the partner. If you find some write in is a fiance, spouse, or established boyfriend or girlfriend, one you left out because you did not know existed, you need to add that person to your list. They will have been together a minimum of 5 months by the time the wedding date comes. You ask the person's name and address, and send another invitation. These are not plus ones, they should have been invited as the guest's SO to begin with . . . . Real plus ones, flavor of the month not a committed or established relationship, are as people say above. They need the suggested, I am sorry, but we can not accommodate your request to add a guest of yours, to our original invitation for George and Lucy. . . . Be polite, specific when repeating names of the only people invited, and do not give in except for very extraordinary circumstances. Like your invited aunt had a stroke and uninvited cousin coming to physically assist her. But not dates where they really, really want them. . . . As long as you invited in social units to begin with, no one has a legitimate argument. You are the hosts. But it is easy to miss a couple of true SO from friends or family you have not seen for nearly a year, so those few are reasonable requests to fix an oversight of yours
