FH's family has NEVER had a big wedding for anyone and some have never attended a wedding. He has a HUGE family so it was shocking to me that they do not have the first clue about weddings (nothing, nada, zilch). We are having a formal wedding, church ceremony, catered dinner and dancing. My parents are hosting and our minimum catering expense will be $8000 at our venue. This is not a backyard BBQ or potluck in which anyone can just show up (or decide not to show up) at the last minute.
Ok, so here is my problem. I am having trouble getting addresses for some of his family members. His aunts keep telling me to just mail the STD and invitations to them for their whole family. They have adult children, with spouses, so it is no it is NOT appropriate for me to mail one invitation to an aunt to include her 5 children & their spouses! I also do NOT want to send 5 invitations to the aunt's address addressed "in care of." This is driving me crazy! What would you do?
