Is AUTHOR wrong in the post ? POST : A bit of backstory: my brother is in the military and recently got married to a girl without telling my family. Last time I saw him in person was last spring and it ended in a huge argument between the two of us due to him flaking on plans he’d made with my mom. Long story short, we don’t get along and I don’t like his wife either. 

But now my grandfather wants to fly my other sibling, my mother and I down to visit my brother and his wife for a week, making a trip to Disney with them as well. I don’t like my brother and I don’t like Disney. And this trip is meant to be over spring break which would be a huge money loss for me since I work in a restaurant in a beach tourist town. I get that my grandfather is trying to maintain family relations and wants to see my brother, but I have zero interest in seeing them at all. But of course my family is all telling me I need to go for the sake of family. 

AITA for not wanting to take a week to visit my brother?
