don't be upset, my brother and sil got married 3 X to fit everyone into the wedding! lol. If the kids can postpone the honeymoon a day maybe they can come to see gramps and you at home all dressed up in wedding clothes, take some pics, have some cake - . Can anyone video it for you? Can you hire anyone to pick up your father and stay w/ him until after you can get back to himlater in the day? Someone from his or your church? Even the minister of your church wouldnt mind I would think.
My brother eloped, then had the whole wedding - west coast - a few months later cus sils mom wanted it, and then 6 mos after that came east to NY and got married (cake, dress, chaplin - ring exchange, reception - no gifts! - food the whole thing) for my parents and family. share t
