Vent but also looking for opinions.

So this might get a bit long. I will be 39 weeks pregnant on Wednesday and my husband works at the other end of the country. He has booked paternity leave from next Friday and his MIL will travel up on Saturday. This is so we have somebody to watch our toddler whilst my husband takes me to hospital when I go into labour, dont even want to think about any chance of labour prior to Friday, we live so far away from both our families that we have no option but have her stay for a while. As much as this is a bit of an inconvenience because I would love this time to bond with our new family of 4, it just is what it is. After all she is doing us a favour. However, we have agreed that we will have no other visitors as it is a stressful enough time and we do not want to play hosts to our families. However, his brother and his fiance have decided they are coming up at the same time as his mum and his youngest brother is currently near by with work so they are apparently all coming this weekend, for the weekend. It is clear that my MIL has set this up so she gets to see all her sons together. I can't help but feel super frustrated. My sister had asked if she could come visit on the weekend after my due date to which I said I cannot say as I could potentially even be in labour late but my husband said, not a chance they are not welcome because we will be to busy. However, there's every chance I could go into labour early, after all its my 2nd and my 1st came at 39+1. I personally feel like I would be a lot more comfortable with visitors once baby arrives than I will be before. My worst nightmare is going into labour and having to worry about a house full of guests. It is such a personal time and tbh I feel like you lose enough dignity at the hospital, I don't need to lose this in front of family as well...and not even my family. Because they all stay so far away I feel like saying they cannot come is just being over dramatic and it is obvious my husband must want them here or he would not have agreed. Am I being ridiculous to think it's a bad time or should I be more understanding and accepting of them visiting. I am also very aware that these are our last few days of our son being an only child and I want to spend time to reassure him there will be no change when baby does arrive (he's only 2). And to top it off because we have said no visitors afterwards it seems I will not be seeing any of my family on the run up to Christmas but we will have seen all of his. I am torn between wanting time to ourselves and making it fair that everybody has a chance to visit before Christmas.
