The tables at our reception venue are rectangular and seat 12 people each. We are planning to put immediate family at the two tables closest to the head table where we and our WP will be seated. For my family, that will be my parents, my two brothers and one cousin (who are the three ushers) and their dates, and my paternal grandparents. My maternal grandparents are deceased. I'm wondering how I decide who gets the last two seats at the "head" family table without hurting anyone's feelings. Any suggestions?
