Guests giving themselves plus ones

I would say call them personally and nicely say that you received the invitation and noticed they added a plus one but that the plus one option has not been made available to stick within the sizing of your guest list. You would still love for them to come but the invitation is just for them and you hope they understand. If they get made then they do not have to come because it is rude to add a plus one when not offered.

The only upset I could see if them feeling like others were allowed but they were not. Even if they are single they may have wanted to bring a friend. I have been to quite a few weddings alone and did not really know the other guests and on a major holiday it can be lonely. You can still stick to your guns but I would ask does it up the guest list horribly? Will you have all the single people at the same table? I agree with what someone else said that they may decide not to come. That is a big holiday and it is great to have your wedding but it might be hard for someone to go alone to a celebration for someone else. I am just playing devil's advocate. Ultimately, it is your big day so you need to do what is best for you and your budget.

Ahhhh I get it. Sucks when people ask to come to your wedding lol. It is fully awkward. Well I think then let them know about the no plus one nicely and either one of three things may happen: 1 - the attend the ceremony but not or do not stay long for the reception 2 - they decide not to go due to not wanting to go alone or 3 - they come. I think if you stress the sticking to the guest list and numbers then that should communicate the message. Hopefully it goes well.

A Plus One is the term for the guest you give someone when they fit that last category - they don't have a significant other or anything close to that. It sounds like what you did was invite people's SOs, which is good and what you should have done, but what PP was saying was that for a NYE wedding it would have been a good idea to budget and plan for Plus Ones for all single guests in addition to inviting all SOs.

I agree with PPs that honesty is the best policy. Call your guests and let them know you're unable to accommodate anyone extra.

Agreed with all those who said to call and explain you cannot accommodate a +1 for them but hope they can still come. If they choose not to come because you didn't want to allow them to bring a random date, then I'd say you probably didn't need them there anyway. If you are already over your guest count because so few have RSVP'd no, then it wouldn't hurt if some of your single guests decided they didn't want to attend if they have to go solo.

I personally hate random +1s and don't understand why there is an assumption that everyone should have to have a date to a wedding. If you have guests with SO's you haven't met I think it's appropriate to invite them, but I think the idea of giving everyone a date just so they don't have to be alone is so unnecessary. Weddings are so expensive and the couple getting married generally want to spend time at their weddings with people who mean something to them, not randos. I've been to at least a half-dozen weddings solo (including ones where I didn't know any other guests) and been totally fine.

My MIL requested two +1s at our wedding (for my FH's sister, who is single/dating around, and his aunt, who apparently trades men on a pretty regular basis so who knows if/who she'll be seeing in 6 months time) and it still irks me.

This is a great way to tell them!
