I said you have to draw the line somewhere (that you were replying to) on page one. I am sure that you also had to draw the line of who to invite somewhere. One does not invite everyone they remotely know to a wedding.
In our case, we had 100 people to invite (family, friends, etc.), DS and his bride each had 50 including the wedding party to invite, and the bride's parents had 100 people they could invite. For the bride's parents and us, this included our close relatives (all of my siblings and their children, all of dh's siblings and most of their children-there are some grown cousins to ds that live 1000 miles away that we knew could not afford to come and that DS sees rarely-they were not invited so it would not look like a gift grab and the same for the bride's side of the family) friends who were a part of our children's lives growing up and some work contacts that we each had to invite. We had to draw the line at inviting my aunts and uncle who live 1500 miles away and have never met ds. My uncle (the brother to these aunts and uncle) who lives in town and has been a part of Ds's growing up was invited. All those very close to DS and his wife were included and invited. Had we really needed to invite 5 or 10 more people that would have been okay, too.
Everyone has a line that they have to use to invite people. That line is a little different for every family. Not right or wrong, just different.
Bride's family paid for a very nice affair and the 300 closest friends and family were invited and there. We paid for a very nice formal rehearsal dinner for 50 people. Do many people have more than 300 close friends and family to invite to a wedding?
