Do grandparents usually get invited to the rehearsal dinner? Asking because I'm not in the best place with dad's parents because they booked their vacation for the day of my wedding and are leaving right after the ceremony, so I'd rather not invite them. And my mom doesn't want me to invite her parents either. But FMIL is hosting it. I would assume she would want to invite her mother who is coming from Florida and also her dad and his wife who are local. Would it be weird if FH grandparents were invited and mine aren't?
