When did you allow visitors after csection?

My husband is upset because I don't want my in laws to visit the day I have my csection (last pregnancy they failed to respect my wishes and showed up with a whole gang of people). I want my daughter to be the first one to meet the baby, then my mom (she's the one watching our toddler while we're in the hospital). Is it unreasonable to want to be showered and able to walk around before letting my husband's family in?
