SO won't tell in laws to get hotel

Okay, two weeks(ish) until my due date and I've given my husband multiple chances to tell his parents that once the baby is born I do not want them staying at our house. I'm the type of person who needs to find a routine without three to five extra people around me. I want to bring the baby home as a family, not with my in-laws and not with my parents. I want people to call before coming over and I want to be able to whip my boob out without feeling like I need to take cover in my own home because his father, mother, sister and two grandmothers would be here. He said since we have an extra room it's no big deal if they stay, but I know for a fact they will overstay their welcome and the one week my husband has off from work will be spent entertaining them and not getting to bond with his child. I know it sounds like I'm being harsh, but his mom is EXTREMELY overbearing, to the point where she had the nerve to call me and tell me that my mother should absolutely NOT be in the delivery room with me and then called to tell her son that since his sister is the oldest and will make the most money out of our siblings she should be a godparent. My sister is a teacher and his sister will be a nurse. I'd rather my child be loved than get money thrown to them, but either way we had chosen a couple that we have been close with for years. She is not happy with that decision and bashed my family basically stating I brainwashed him. His sister is a snobby little thing who will text me saying how awful childbirth is going to be, mind you she has no children, no boyfriend and is still in school. She also told me to make sure to have "it" on a Friday because she will "make" her dad buy her a plane ticket down here for the weekend so she can be the first Aunt to see him. My sister won't be able to make it down until the end of April and although she is sad, she understands that that's life. Not to mention they are loud and have no respect for other people's space or wishes. Since it's getting down to the wire should I write to them to let them know they'll need to find some other arrangements? (Adding anon in case my crazy SIL has this app to check up on me )
