I'm looking at invitations now, and iim thinking instead of sending out rsvp's to send reception cards. The ceremony and reception are going to be at the same location. On the reception card I'd indicate adult only reception to follow, with the date I need responses and asking guest to either all or email their rsvp's. I would prefer for people to call or email instead if mailing back the response card, that way ill avoid people trying to bring extra people that wasn't addressed to come. What's your thoughts on doing that?
