I went to Warwick many years ago and I will say that as a Londoner who was very into clubbing I was worried at first. However there were a lot of coach trips to Birmingham and I pretty much went on one of those every week from memory. Don't even know if students go to clubs now.
I absolutely loved my time there and wouldn't change it for anything. I'm mid 40s now and still friends with my first year halls friends. You do build very close relationships at a campus university. It was wonderful.
Leamington is a fab student town to live in with lots of pubs etc. I was lucky enough to have a car but did use the bus a lot for nights out etc.
To the PP who said Warwick was ugly and uninspiring - yes it's a modern university but frankly I found my lectures and some of the teaching so inspiring it has influenced my whole life.
Also, Warwick Arts Centre right on campus. It's such a privilege. I went to a film premier there and got to interview the (famous) actor for the student paper. I watched tons of films, theatre and concerts there and my first opera. So much culture. I meet up with my Warwick friends now for the theatre a few times a year.
That said, my DC who are teens have already said that campus life is not for them and they want to go to city universities. Also, I went back for an event last year and it did seem that the union looked pretty boring on a weekend, but obviously a current student could confirm what actually goes on.
