Worried I've picked the wrong college at Durham?

Initially I wasn't expecting to want to go to Durham, and I chose St Chads as my college choice rather quickly. Now I am starting to seriously consider going to Durham University, and after finding out I've got into Chads, I don't know what to think.

I've tried to do some research, but struggling to build up an image of each of the colleges. I knew I wanted a traditional college with formals (and I love the idea of being on the Bailey). I'm not religious so I ruled out St Johns, and steered clear of Castle because of how competitive getting in would be (so more chance of ending up somewhere I really don't want to be!). I've also heard that only a small percentage of the rooms are actually in the castle. Bad stigma about Hatfield kept me from applying there, although now I realise I might actually like it, seeing as I could be considered posh and I like rugby guys. Beyond that I hadn't considered any other colleges, especially as the more modern colleges weren't that appealing to me.

I would say I am hard working, but I do enjoy going out and partying a fair bit. Any ideas if I would fit into Chads? Or any information you can share about any of the colleges would be really interesting please
