I am in the middle of customizing my invites and RSVP cards. Most of our guests are entire families (for example, we are inviting most of my fiance's cousins and their entire families). Since we will only be sending one invite per family, would it be strange to include multiple lines on the RSVP card so that the families can list the names of those who will be attending? I keep imaging getting one RSVP back and finding out at the last minute that not all of them will be coming. We will be having around 250 guests, so I would like to be as accurate as possible with the head count and place cards.
Thanks!
