I read that the return address on the invitations should be the same as the address where guests will mail their RSVP cards. But, we are having our guests RSVP on our website, or if they don't want to do that they can call my mom to RSVP. I will be managing the online RSVPs and my mom will let me know if anyone calls to RSVP. I have also read that the return address should be whoever is hosting the wedding. Both sets of parents are hosting and paying for the wedding. So my question is whose address should I use as the return address for the invitations? Also, do I include names with the return address or just the address itself?
