So Im worried that people wont understand wedding ettiquette and will bring dates or guests to the wedding. On the invitations I made sure that there was no place to add in guests names or put +1's. The main reason for this is that it is $190 dollars a head, and my aunt is paying for the entire wedding. FI and I both agreed that we would keep the invite list small on the small side; there are only about 85 guests invited and 75 expected.
I've already run into problems with this. One of FI's friends started talking about how she and her boyfriend were so excited to be coming, and that they both got time off of work already. She was the only one invited, and though her boyfriends name was no where to be found on the invite, she just assumed he was invited anyways. Don't get me wrong, I like the guy, but there are other friends and family I would have loved to come that I didn't get to invite due to to the agreement FI and I made. I have more friends whose significant others did not get invited and Im afraid of this happening again. How do I politely tell them all that they cannot bring anyone with them whose name was not on the invite? Any suggestions? Has anyone else had to deal with this?
