Labor time HELP!

I'm 30+5 with our 3rd baby #teampink.  With my first baby I had my aunt be in the room with me, the second one was my mother in law and my husband. This time around I only want my husband to be with me. I want to experience the both of us welcoming our baby.. I don't know how to tell my mother in law I don't want her in the room or my brother in laws wife. They are both traveling 15 hours to help out and they both are expecting to be with me. I don't want to sound rude when telling them, so please help me with some advise. Thank you!
