I professionally addressed all of envelopes for our invitations. On the invites, I included the names of the people we were inviting (for example, Joseph Fl****). We are not inviting plus ones as this wedding is small and just our closest family and friends. Do people assume they get a plus one? I asked our guests to RSVP on our wedding website where I made it so that they could only reply for their party (for instance, Joseph can only click 1 will be attending). Is this enough or do you think people may assume they can bring a guest? Do you think I should mail our RSVP cards as well where it is more explicitly stated that their invite is simply for them? If so, how should I state this?
