We are having our grandparents and parents seated before the bridesmaids walk down the aisle. I am unsure how to do it exactly. Who's grandparents go first? Do our dads sides go first or our moms sides? Also, if you are having ushers seat them, what happens if they are married? I know our grandpas won't want to have a guy hold their arm and walk down the aisle lol. Thank you for the help, i've tried googling this and have found a million different answers.
