My DH cousine who I dont really know wants to stay 4 nights with us. She has a reputation and none of the other family members want her and have excusses lined up. We havr a 15 month babby. My Dh agreed for her to stay and I accepted but now she wants to bring a friend along who neither of us habe met. We have a family wedding so I am oblidged to help but I am really uncomfortable having a total stranger living with us. We both work full time and the expectation would be to leave house keys behind.
