So we decided to go with the whole 'no ring, no bring' adage in order to keep our guest list a bit shorter. Our RSVP cards had space for a name on a line, and a short blank beside 'accept' or 'decline'. We used outer envelopes clearly addresses to formal names, and inner envelopes with the name of the person invited, sans guest. RSVPs just began coming in last. FOUR guest have already added their guest. They put 2 on the line for accept. Two sent an email to ask if it was okay 'because our invites didn't specify whether they had a plus one'. Did we do it ALL wrong? Can we tactfully tell them to keep their extras at home? And if so how do we do this? Sorry - a little stressed. Venting a bit... TIA!
