I'm trying to nail down my rehearsal dinner guest list so we can decide on a venue. One of our family friends is singing at our wedding so we definitely want to invite her to the rehearsal/dinner. Her entire family (husband + 4 kids) is invited to the wedding, so does that mean all of them need to be invited to the rehearsal/dinner as well? We are also having about 6 other musicians sing/play at our wedding. Should they also be invited to the rehearsal dinner?
