My FMIL lives out of state and so does FH's girl cousin. They and we know that they're not going to fly into Hawaii three months before the wedding to attend my shower. His cousin specifically told me to let her know when the bridal shower is. Do I just let FH's cousin know the date and not send an invite? Do I even send an invite to his mother? I don't want to seem gift grabby but I don't want to NOT invite her, either.
ETA: clarification
