AITA for not wanting my SIL to come with us on vacation?

Hi,

It will be our first vacation with our daughter in early August. I also invited my MIL (who im verry close with) for many reason. So she could be away from my FIL,go on vacation this year and also to spend time her one and only granddaughter.

The apartman where we going to stay is my fathers. He is also going to stay there do to some business meetings. So we are going to be packed. The apartman has 3 bedroom and a couch. Im going to stay in one with my daughter(my husband snores to loud),husband and MIL inthe other 2 and my father on the couch. (We organised this at March).

My SIL break up with her boyfriend do to cheating (she cheated) a few weeks ago. Since then she comes over uninvited and to talk. I would not care becouse I like her but she comes at night when im doing my daughter night rutine (she is theeting so its a lot harder).

Today my MIL told me that she will bring SIL so she can have a relaxing summer. I told my husband i dont want her to come for many reason. We would be kike sardines in a can,I organised this over half a year with baby friendly stuff (she is a party girl so Idk if she would even like it),my father dose not like unknown people (she saw her once at our wedding). And the biggest reason is that I do not like when my plans are just being looked over. I organised this,I made resovations to restaurant and I made plans for programs. I know not everything can go as planed but this is too much.

My husband said im am an Ahole,becouse I kind of dont want to go like this anymore.

So AITA?
