My daughter is getting married October 13, 2018. The caterer we are using (highly recommended by both the venue and several past clients) is requesting a 30 day final count. In order to allow a bit of wiggle room for the late responders that might need prodding, I figure we would need RSVPs due 6 weeks prior to the wedding, and then invites sent out around 10 weeks prior. Do you think this is too early?
