Hospital visitor list

What is the best way to limit who visits you in the hospital? My husbands uncle is very creepy and annoying to me but is best friends with my MIL (in fact he lives across the hallway from her). I absolutely 100% do not want him coming with her, which I can definitely see happening....but I don’t want to be rude. Should I just let my husband tell his mom to not bring him?

Any advice is appreciated. TIA.
