We are sending out 2 tiers of invitations. Basically our guest list got out of control, so we decided on a certain number to invite to begin with. When we get "no" RSVP's, we will send out a second tier of invitations. That being said, what should the timing be for the first round of invitations to be sent out and to request the RSVPs back? I know normal timing is 6-8 weeks. Just wondering if I should do earlier to allow more time for the 2nd tier?
(As a note; I don't care much about the 2nd tier guest, this is to make my FMIL happy)
