For example, I have an aunt who is divorced and has two children. She and the two kids are invited, but I also want her to have the option of a +1. How do I put something like this into the RSVP? I’ve heard of options of putting each person’s name with regrets/accepts next to it so I know exactly who is coming, I like that idea so that I don’t end up with too many uninvited guests but how would I do it with this? Or even if I don’t use that format, just how do I do this period?
