Would you do this knowing it was not part of the friends plan?

Today in the evening, Im meeting with some friends to catch up and chit chat. We were all former high school classmates and only from time to time we gather, not very often though.
Today was supposed to be a only ladies night out (no partners, no boyfriend no husbands, no children either) Im single and no kids so I have no issue anyway.

So today that I was informing the friends about the chosen venue, one of them suddenly told me: "Im bringing my daughter and my husband, because we have to pick our daughter up from high school and after that we arrive at the restaurant, so please book 2 more seats".

When I was organizing this get togehter with another friend like one week ago and we started to inform the other ladies this friend in particular never mentioned us she was going to bring her hubbie and one of her kids, we assumed (like some past occasions) she was going to go alone but today that it is the get together, she mentioned us all of a sudden she was going to come with her hubbie and her teenage daughter.

Now for that tiny dumb mistake this friend did, I had to tell the other friends to bring her hubbies as well, if they want and can, because it be impolite that only one brings the hubby while the other friends may wonder why one could bring thier hubbies, while they can't.

I mean the plan since the beginning one week ago was girls night only but then today unexpectadly this friend told me "she will bring her hubby and daughter beacuse she has to pick her daughter up from school and then she arrive at the get together".

Well the gathering alreayd took place and it was not as bad as I thought it could be. Three ladies brought their husbands out of 7 ladies invited, but at the end it was not as bad the husbands also took part of the conversation.
