To each his own, but here's my official stance: a wedding is a union between not just the bride and groom, but between the two families as well, so why the Berlin wall when it comes to seating? Isn't this the time to mix and mingle and get to know each other? And what better way to do that than by having the families sit together as they watch their loved ones say "I Do".
Did you have separate seating for guests at your wedding? Will you when you get married? Have you been asked to pick a side at a wedding and how did you feel? We'd love to hear your take.
