So, deadline was 3 days ago. Got another RSVP in today (still waiting on 65 people) and it was from my uncle who lives up north, I invited him + his wife, he wrote that EIGHT guests will be there on the RSVP. that's SIX additional guests. HOLY CRAP.
Thank GOD this is a hor d'oeurves + drinks kind of thing and NOT a sit down dinner!!!
