What to do?

I am having a bit of a mental dilemma regarding Thanksgiving. Do I go to grandmas like normal or do I stay home and go to the honey's nephews.
I know what I want to to which is go to grandma's but honestly I want to be fair too. The honey would like to go duck hunting for the first time this season the Saturday after. He has worked every Saturday so this would be his first opportunity to do one of his favorite things and he actually really deserves to be able to go. He is working so damn hard. He is leaving the choice up to me.

So here are the choices.

Drive up to grandmas after the honey gets off work on Wednesday. A 3 1/2 hour trip one one.
See grandma has slowly but surely handed over the cooking to me. I am the holiday cook. My entire family on that side comes over and we feast. We talk and play card games. This year one of my cousins is actually going to deep fry a turkey so I wouldn't have to cook that. I am not sure who would do the rest of the cooking if it wasn't me.
I would want to stay and go see the Harry Potter movie with my grandmother since it is kind of a tradition also. But I would feel the need to leave the day after Thanksgiving in order to give the honey the opportunity to go duck hunting. So that would mean no movie.

The other choice is staying home and going to Thanksgiving at his nephews house. This is the first time they have ever done a holiday gathering. This is our first invitation to something like this from them. The honey doesn't spend a lot of time with his side of the family so this would be nice for him. He would also be able to go duck hunting that Saturday and possibly that Friday too. Something he really wants to do. It would also mean he didn't have to drive 3 1/2 hours after work and then 3 1/2 hours home the day before hunting.

My inner want is grandma. But like I said I want to be fair. I also don't want us to separate this Thanksgiving because it really looks like that might happen on Christmas. The decision should be easy. Let the honey stay home so he can have some much needed down time from his job. He has been working weekends for months now. I feel selfish for wanting to spend time with my family. I am completely torn. HELP!
