Spending Thanksgiving with my BF

So I'm spending Thanksgiving with my boyfriends family this year, instead of mine. We're all going to his aunts house about an hour away and to avoid traffic on the way back his family is just spending the night. We are not sexually active, nor do we plan to be until marriage. I am 21 and he is 23, but I don't think my dad will allow me to stay the night, but I also don't want to drive back alone and if my bf drives back with me, he has to spend the night alone at home since his family will be at his aunts..
