So dh got home round midnight last night. And I vented about 10seconds after he sat down. (I admit, he asked me how I was and I couldnt be bothered lying to him)
There was a few issues. He did the same at christmas, my birthday was a non event, every week our days off are overtaken by trying to please his parents. I explained that he needs to focus on his family for once, his immediate family not his extended family which his parents are part of.
I also explained to him that all week, every day the girls non stop talk about him, not his parents, no one else. Its all about him, so when he has days off they want to spend it with him not the rest of the world. Easter and other celebrations are the same. They want to share their joy with him, and the girls are not saddened by the idea of having two or more easters and christmas's if that is what it takes to please everyone. I was in tears, i got everything off my chest.
As far as tomorrow is concerned, he said he would cancel them coming over by saying that he had to work early. Downside is that they would have still showed up anyhow, and I would be stuck with them by myself..

Thank you for your words and encouragement. I feel better for getting it off my chest.
