Do we only invite those that are in the ceremony? I'm not sure if we invite FI parents since they don't have a role in the ceremony. I know we invite our bridal party, their significant others, minister and my parents, but what about his? We are thinking about meeting everyone back at the hotel bar for an informal gathering after the rehearsal dinner, although his father isn't staying at that hotel (something about being able to use his marriott points) and doesn't drink.
