Baby's first Christmas...where should she spend it if her parents aren't married?

I already asked a version of this question but I'm hoping that if I rephrase it differently I can get more unbiased answers. So...where should my baby spend her first Christmas? Her father and I are not married but in a happy relationship. But we have our families saying different things. Looking for advice, not insults please. Oh and I'm putting this question in the newborn/baby section because I'd like opinions from parents or people who have experience with children and/or this kind of thing.
