Who will be in the birth room? Or who was?

I am having a mental stress dilemma my whole pregnancy my bestfriend has wanted to come into the birth room. I've been reluctantly been saying yeah sure but deep down never really wanted to and now my mum wants to come in as well. I only really want my partner in the room... just to have that moment to ourselves. Is that too selfish? And even the first hour bonding time and then i will happily have visitors. Mind you my bestfriend had her baby didnt have any visitors the day of her birth (not even me - she only wanted her partner to go to all the appointments and what not) shes been to most of my appointments as well. I think i have been very lenient with it all and am having trouble putting my foot down to tell her that i truly only want me and my partner in the birthing room. I am currently 40+5 and will be getting induced at 40+9. I tried to tell her today and blame the excuse that i dont want my mum in the room (shes very loud and wants to take horrible photos of me) and that i will be kicking them both out just to not hurt my mums feelings and then she turns it around and says she will talk to my mum so she doesnt act crazy in there. In all honesty i just want it to be me and my partner. Some people want everyone in the room and its not me. Im sure she would understand because she didnt want anyonr but her husband as support. But i have a feeling shes going to get really angry and frustrated just because she has been there for me the whole pregnancy. Anyone in a similar position or was? What was the outcome? I dont know how to break it to her before tuesday :/
