I'm getting ready to send out invitations for my wedding and I had a question about how to address the envelopes to include "and guest". I've seen a lot of answers suggesting putting the "and guest" on the inner envelope or even filling in the rsvp with "and guest". The question I have is, what do you do when you don't have an inner envelope and you are doing online rsvp? With online rsvp you have to input each guest individually. My initial thought was to put the guest in "Jane Doe" and then include their plus one as "Guest Doe" so they can see that they have a plus one when they go to rsvp. Should I also include "and guest" on the wedding invitation?
