Yeah it's hard isn't it, it's all really rushed! And it's annoying that it's the weekend 'coz some of the Unis don't answer the phones on weekends! Have you compared the costs of halls and what the local area is like for each Uni?
I've just been looking at the halls again and it does look like the Bakery is better for me as it's closer to the train station. I'm going to call Glamorgan on Monday and ask them about it.
