hey, I guess there isnt much you can do but follow their rules
It is their home and whenever you stay at someone elses home you have to respect what they say. one approach that may help is talking to your husband. Explain to him how you feel and maybe he can talk to them and tell them how you are feeling. You can even try explaining it to them yourself. My I love my In-laws but girl I give you credit I could never live with them...even temporarily lol
