Two of my fiance's groomsmen have just let us know that they will not be attending the rehearsal at all. Our wedding is in 17 days. For both of them, they are coming in from St. Louis to Chicago where the wedding is. I don't really know how to reiterate to them that the rehersal is really important. One of them just recently got married and his now wife would have flipped out if two people were not showing up. The second one just recently got engaged, so may not know that the rehearsal is important at all. I know I cannot force them to come (they basically forgot to ask off work until now and thier bosses now said no). How do I run the rehearsal without them and how do I make sure they get filled in properly before the ceremony the next day so that everything goes smoothly? We are having a full Catholic ceremony and neither of them are Catholic so they don't really know any of the differences...
