Upset Abt nye plans

I feel like I have a bad attitude but my
Husband and I are taking his kids from a previous marriage back to the town the youngest was born in for new year <a href="">eve</a>. He planned spending
A day at a place where he said that him and his previous wife and kids would go all the time. I said we could have gone somewhere you haven't been to a million times with your wife before me, he just rolled his eyes at me
And said that the kids wanted to do this..... The oldest was only 3 and youngest a baby when they moved to my hometown so I find it hard to believe that they even remember it. 
I don't usually feel this way so I am assuming it is the hormones but wanted to know if I'm
Overreacting by being a little upset?
