SO.. we sent out invites last week and Iam a little freaked out that everyone will RSVP yes. Not counting out of town people we know won't make it we invited 180 people. We are hoping only 150 RSVP. Did any of you have more people than you thought RSVP? I tried to go by the 80% rule which would put us at about 140-145 but now Iam worried
