Privacy

So I have a scheduled c section 11/26, I had let family and friends know that the first day, I do not want any visitors, due to me just having surgery. A little bird told me my MIL is going to take a bus to the hospital that day, against my wishes. My own mother is not going to be there that day. Do most hospitals have the ability to not let any visitors to your room per your request? I am a very private person and I would like to have a private day with my husband and my new borns. I’m so livid that she is trying to be sneaky.
