Advice about company during labor !

Hey ladies I need some advice about when I'm in labor and what to tell my MIL. My husband and I live 2 hours away from both of our family. We agreed while I'm laboring it will be Him and my mom in the room because I feel completely comfortable with them seeing my lady parts I plan to get the epidural but I want to labor without for a while the use the jacuzzi tub and birthing ball and I don't want to worry about family member peaking in while my butt it wide open on birthing ball haha. Since we live so far away and this is my first delivery idk how long I'll be in labor hopefully not long but I know it's could be days so I don't think it is reasonable for my MIL and FIL to sit in waiting area while I'm in labor. My hospital is also very passionate about chest to chest and recommend it for the first hour or two before the baby is weighed and etc so we want that bonding time alone so I can try to breastfeed as well so that would be an additional 2 hours of them waiting. It stresses me out to think of people waiting I'd rather call them right after the babies are born so they can drive our way then which would be perfect because it would take about two hours. My husband said he's not going to tell them they can't wait but I'm ready to just tell my MIL not to come until I say so. How can I tell her this without her taking it personal. She is a very pushy and over bearing MIL so I have to say things a certain way or she will get either emotional or pissy. Thank you !!!

Also to mention I am high risk due to having twins so I will be pushing on the OR and I also have I high chance of a c-section
