Interestingly enough, in my first year I had two friends on my course who lived in Kenilworth - one decided to move into halls on campus, and the other stayed in Kenilworth and just got the bus in.
I honestly think it makes absolutely no difference. If you're a social person and want to socialise or make the most of opportunities on campus - you will do whether you live there or not.
I had moved out of my parents and lived with my bf before I came to Uni - and I thought I'd give halls a chance in first year, but now carry on living with my boyfriend (we live about 30 miles away from Campus so MUCH further away then Kenilworth) and I can honestly say that I have been more social/taken up more opportunities and am 500% happier living at home with my boyfriend than on campus. BUT, you may be completely different!
Life is what you make it!
