Hi ladies--
I'm trying to start working on place cards. I will only have assigned seating by table (I only assign the table and they're free to sit whever in that table). On the place cards, do I put their formal names or whatever they put down on RSVP? I sent out invitations with their formal names (e.g., William, David), but on the RSVP card they wrote their nick names (e.g., Bill, Dave). It probably doesn't matter anyway, but what's the protocol? If it helps, the wedding/reception isn't super formal. It's a lunch reception in buffet style.
Thanks for your help in advance!
