I know it is customary to have the Bridal party and immediate family of the bride and groom at the rehearsal dinner. My fiance is one of 9 children and none of our bridal party includes any of our siblings. Our bridal party, including the two of us, is already 24 people. If we invite our siblings and their spouses and children, we are looking at close to 75 people. That's a wedding in itself!!! We are paying for our wedding ourselves, so would it be rude to have the rehearsal dinner for the bridal party and our parents only? We don't want to pick and choose certain people to come so it would have to be all or none. Please help!
