So, my parents want to host a brunch for out of town guests the day after our wedding. I think it's a great idea, and I'm really excited for it (even though my dad thinks we should leave for our honeymoon right away and not see guests after the wedding.. sigh). My question is, when/how do we send out invites? My dad insists that we have an invitation to the brunch included with our invitations (on a separate card). My mom thinks we should send out invitations to the brunch on their own, before the RSVP deadline is due, especially since not everyone on our guest list is invited to the brunch.
What is appropriate? Is there etiquette for this? Thanks!
