We're up to about 200 invitations all together, including those to people we know won't be able to make it. Plus, couples and families just get one. We had about 135 guests show up 2 years ago (plus 15 service providers). Last year we dropped down to about 110 guests & 10 SPs. This year, we're expecting another big turn-out.Really unique idea! How many people do you invite to your shindig?
