We have decided to not have "plus ones". This is not a budget issue. We just feel it is silly to have people celebrating your wedding who you have never met before. We have about 15 people who were not offered a "plus one". Everyone is OK with it with one exception, the FSIL, who is also a bridesmaid. Other guests and bridesmaids do not have a "plus one" and they understand and have no issue with this.
Here is some more info on the situation, because I need some other points of view! She is in her mid 20's, still living with his parents, and when she found out, she threw a temper-tantarum (I'm not even exaggerating). She has been casually dating someone for a few weeks now and insists that he is invited to our wedding which is in 3 months. She has now gotten both of his parents involved and my poor groom has been receiving angry emails and phone calls from them over the last few weeks. My groom is beside himself that his family is acting that way and we just don't know what to do. He has told them all how we feel about having strangers at the wedding. He has also shared how as a bridesmaid, she will be busy for all but 3 hours of the day...so what will her guest do the rest of the time(he won't know anyone there except her)? He has also reminded them how this is our wedding and not a summer BBQ with an "open invite". Lastly, he reminded them that this is his day, not his sister's day, and he expects his family's support.
Has anyone had anything happen like this? What do we do? His family "listens" but doesn't really hear what he is saying. My guy is a wreck about this and I need some help!
