So my FMIL invited a bunch of her friends to our wedding. Because my FH does not have a lot of family, we agreed it would be okay if her close gal pals were invited (I have never met them). Now we are receiving their RSVPs and they have included their boyfriends (WHO WERE NOT INVITED). We specifically put on our RSVPs that we had 1 seat reserved, and they changed it to two. I don't really know what to say about it to her. My FH says it will be okay, but we are quickly running out of space at our venue. Also my family is paying for most of the wedding, with my FH and I contributing. I really don't want to be rude, but I'm not sure if we can fit their boyfriends. Should I speak up to her now, or wait till we get more RSVPs and see if we can fit them?
