Are you inviting your future mother in law to get ready with you on your wedding day?

Hey all! As my title suggests, I wanted to see if people were inviting their future mother in laws to get their hair and makeup done with them on their wedding day. I was not planning on doing so. My mother and I booked a professional stylist to come to my hotel room for just us two (I have no bridal party). Today I received a text from FH asking if his mom, step sister, and cousin (cousin who I've never met) could also come to get their hair and makeup done. I have serious reservations about saying yes. First reason is me and my FMIL are just not close. Second is my FH comes from a divorced family and I cannot invite his mother without insulting his stepmother. Is it rude of me to advise my FH's mom to just contact the hotel and hire someone for themselves?
