My fiancee and I are working on our guest list and need to cut it down a little bit. We both have large families, but want our friends to be able to attend as well. If all of our family friends and friends were able to bring a guest (and did so), we would have 350 people attend. Yikes! We need to keep it around 200-225 people. Is there a polite way to tell our (single) friends that they can't bring a guest?
