My stepmom, who is giving me somewhat of a cold shoulder because I am not having my step sisters as bridesmaids or my dad walk me down the aisle, has asked how we will be seating the parents in our ceremony. We do not have any ushers. What's the norm for this? I figured we would just have sets of parents walk in during the processional and seat themselves in the reserved rows. Do the parents walk in before or after the groom? Would I be in the wrong if I just had all of the parents seat themselves before the ceremony even starts?
