Ugh in-laws!

So with my 1st child my mom and sisters threw my co-ed baby celebration at my house which I loved having mine and my SO friends and their families around celebrating our arriving son. Well this time around I asked my MIL and SIL to help me plan it and they said they will do all of the planning and not to worry....well come to find out they want it on a sat at the end of Oct....well me my family and lots of work retail so its hard to get sat off, sun yes sat not so easy, and at a tea house...and don't want is to have any say or input...um personally not a fan of tea and lil tea sands and such and why are they not listening to our wants? How hard is it to plan a co-ed & family friendly celebration of our lil girl? That is all we want not a fancy tea house baby shower. Please tell me I'm not going nuts!
