Thank you for your replies, it's nice to hear lots of different opinions, they have all been helpful in one way or another!
elstevens, What you said about the London opportunities is probably the biggest win for QMUL, when the tutor was describing the course titles and content it sounded so fun and interesting, argghhhh decisions decisions!!
And I agree about the QMUL tutors showing real enthusiasm for their subjects, they really enticed me into the course when I was at the interview.
However, this was quite the opposite at Bristol, during the Q&A session the 3 tutors answering the quesstions were quite clearly struggling to answer basic questions about the course and it's content. Also, during the worshop 2 other tutors running the activities seemed quite scatty and were really vague about things... I'm not sure if this should have an effect on my decision?
At Warwick there wasn't really much chance to see what the tutors were like - a couple of them gave a presentation and seemed very knowledgable and confident in their subject - but because the course has so many students I don't know whether the student/tutor relationship will be very strong (although I've been told quite often the teaching at warwick is amazing and very supportive)
anymore opinions/experiences please share!!
