My rehearsal dinner is what I believe to be on the large size with the amount of people that I have in my bridal party. I'm trying to decide if I should invite the cake servers, guest book attendants, and the girls that would be handing out programs. Am I obligated to invited the people that are helping but aren't in the bridal party? I am also having problems deciding on who to invite to watch us open gifts the next day. I'm trying not to hurt anybody's feelings. How did everybody decide who to invite?
