As others have said, don't go! Not that hard. Mind you, I say that, but some people have zero assertiveness skills. One of my friends, says EVERY YEAR that she does not want to go to her DH's aunt and uncle's house for the 'family quiz' that his uncle creates... It's Christmas night every year from 4-5pm til about midnight.
His uncle (aunt's husband not blood relation) is always pissed by 8pm, flails about everywhere, dominates the conversation, and gropes all the young women he is not blood related to - his nephews wives and girlfriends, and his sons wives and girlfriends. (Even his brother's wife!) Creepy as fuck, but people just say 'oh you know STEVE, he's just like that when he's had a few drinks!'
(God knows why his wife has stuck with him for 33 years!)
Anyway, every year my friend still ends up going. She goes, and then spend 3-4 weeks in January moaning about it. I tell her she has agency, and can decide to not go even if her DH goes. She said she doesn't want to be left alone on Christmas day from 4pm, and go to bed alone, and doesn't want to offend her DH's family. 
Some women do need to be more assertive, and start saying NO to their men, and their mens families! Stop being a walkover. No WAY would I keep going. Nor would I keep going to my DH's aunt and uncle's place if I was my friend.
