I am on a VERY tight budget, but plan to have a rehearsal dinner at a local italian restaurant I am getting a deal on because I know the owners. My wedding party is 12 people, plus our 4 parents, my brother, and the officiant (uncle). So that alone is 20 people. In my mind, the rehearsal dinner was soley for the people in the wedding, as we would be rehearsing what we are doing for the ceremony, practicing entrance dances, and bonding as a wedding party. When I told one of my BMs about this though, she acted rather shocked and appalled that her husband wasn't invited. Is she in the right here? If I let SOs come, that's 9 more people added on. What are your guys thoughts?
