It's absolutely fine, you've made a good choice (in my opinion) and you'll have a great time there (assuming you get an offer and chose to accept it). People will point out things about Hatfield that their college is better at, and you'll suddenly start thinking "Oh no! This place is awful!", but what they won't point out is that Hatfield is better at other things that their college is rubbish at. They've all got ups and downs, and it's up to you which set of ups and downs you choose. One of the downpoints (which has to be mentioned really) of Hatfield is that everybody seems to dislike it (mainly because you're "supposed" to do so), so you might get a few negative comments on here.
Oh, and by the way, I'm a Castleman, so I'm supposed to hate your college the most of them all, and I wrote this, so there we go. It's not really hate, it's teasing.
