During the ceremony planning process I am always asked by my couples "which side does the bride's family or groom's family sit on?" Or does it all matter?!? Traditionally in Christian ceremonies the bride's family sits on the left and the groom's family sits on the right. But these days most couples just want everyone to sit wherever they want, a nod to the combining of the two families. If you choose this more casual route, then be sure to give your guests the heads up with cute signage, ceremony markers, or by having ushers to explain it to your guests as they assist with seating. Giving guests a little direction will allow them to feel comfortable where they are and avoid any last minute seat change manuevers.
