Don't Bring Just Anybody!

Lol my family's motto for non-family members is "no ring, no bring".

We are being very stingy with the plus ones because we're having a small wedding. The only exception to this is people who may not know anyone else at the wedding, but that's only one person and she's been in a long-term relationship for a few years now.

The best way to specify that it's only the one person who is invited is to address everything specifically to them. On the RSVP card you can only have one space for a response so that it's clear they don't get a plus one. And if they ask, simply say it's an intimate wedding and the guest list is limited. (it's a win-win because they'll feel special for being invited, and you won't have to worry about them bringing a rando)

I would only give those in relationships a plus 1 and if anyone asks, just say that you have reached your guest limit and cannot accommodate any extra guests.

Don't give a plus one.

Don't give anyone who is single a plus one. You can't give someone a plus one then dictate who they bring.

The only people who are getting plus ones are people who are in official relationships and anyone in the wedding party (I just feel that if you're spending that much money to be in my wedding you should get to bring a date!). I also will be utilizing the Knot's RSVP feature (as well as cards for older folks) which only allow the named guests to RSVP!

Anyone who tries to add people will be receiving a polite phone call from whoever's side it is!

So I am having the same problem so on my RSVP i clearly wrote and nicely

We have reserved -- number of seats in your honor!

A guest's partner is not a plus one, but another guest of the bride and groom, invited by name--you invite both members of a couple; they are a social unit.

A plus-one is the guest of a guest--entirely optional.

Agree with the others, just make the invite for one person. If they try to add someone, you'll have to correct them: "I'm sorry if there was any confusion, but the invitation for the wedding was meant for you only. We hope you understand and can still come celebrate with us!"
