Should I bring my dog to my parent's or not?

I am going to my family's house this weekend and my fiance is staying home. We have a 2 y.o. Cocker Spaniel/Shih Tzu mix and she is well behaved. However, I am undecided as to whether I should bring her or not. If I don't she will be alone most of the day tomorrow and my parents may get angry if she doesn't come. If she does, she will have a 6 hr car ride and since we are going camping, she won't get much freedom and she may miss my fiance.....she has never been away from both of us more than a day. I am not sure how she would do without him and she is kind of attached to him. So what should I do? Thank you.
