What is the protocol on people that you met after you sent out the invites, but have gotten pretty close to and really enjoy their company? Me and FH started going to play D&D with our former roommate/best man and his new roommate and a couple other people in their group. We sent out our invitations a little early (a little over 8 weeks) because my family are all halfway across the country and this is definitely a destination thing for them. I know a month or two isn't that long to have known people, but we really like them. With my parents/immediate family not coming, my metaphoric side of the aisle is a little sparse, and there are a lot of people coming from his side of the family that I've never even met, so it seems a shame that I have people at my wedding I don't even know while leaving off people whose company I really enjoy even if I've only known them a short while.
