Would this make me a bad mom? It's just one night 😔

So last November, my boyfriend surprised me with annual universal tickets!!! It came with a free Halloween horror nights pass. Fast forward to February, i find out I'm pregnant! I'm due in early October, I'd love to be able to go on oct30th up to Orlando for Halloween horror nights. He paid a lil extra on the annual pass so we'd have these tickets and I don't want them to go to waste. I've never been. We'd leave our babygirl with the grandparents for a night, would it be bad if we went?😓
Edit: thanks everyone! now I'm excited 😊
