Someone did it before I could; a grouping of wedding planning spreadsheets! I'm such a nerd and totally would have made something like this -- it is so awesome it is already made! It has sheets for a guest list, vendor contacts, packing list, wedding weekend spreadsheet, day of timeline (morning AND evening).
