I have begun receiving RSVPs back from people for my upcoming wedding. However, so far I have had three returned with more guests coming than I invited! For example, I sent an invitation to "Mr. & Mrs. ____" and they RSVP'd with four people. Another one of the invitations was addressed to my friend as "Jane Doe" and she RSVP'd and is apparently bringing one of her sisters. Yes, I know all of the "extra" people invited - but my fiance and I decided NOT to invite them for a reason. (We are trying to keep the wedding small and intimate and saw no reason to invite these people). However, either my fiance and I or both of us are close to all of these people. I would find it hard to say "Please don't bring those people". So far, an extra four people won't be that big a deal - but I'm a little worried about this trend continuing. What should I do?
