So we're having a DW in Las Vegas and the ceremony only seats 60 (no exceptions). I posted here about two weeks ago with a dilemma about my FFIL inviting about 10 extra guests and only having them come to the reception. I heeded the advice of WW and agree that's not the best idea and would be really crappy for those 10 extra guests.
So now my thought is to send two rounds of invitations. Our wedding is in June of next year. So I figure we'd send the first round of invites in January with a reply date of March and once we ascertain the amount of guests who won't be in attendance, send the second round of invites (making sure to not exceed the 60 person limit) in March with a reply date of May. I understand this is B-listing, but I'm not too concerned about that. My question is about sending invites six months in advance. Thoughts?
EDIT: The March RSVP date would make it 3 months away so people would generally know by then if they intend on purchasing a flight. Right?
