Our wedding will have roughly 100 guests. Mostly family from both sides, and then a few close friends. How necessary is a seating chart? I have been to qutie a few weddings and none of them had seating charts. However, I did notice that some people at the receptions were a little upset because they ended up sitting by people the didn't know, didn't like, etc. because it was the only place to sit once they made it into the reception. So, is a seating chart really necessary?
