Anyway, we are just back from Warwick, which we liked very much. Similar size to Nottingham I would say, but a bit more modern feeling, there aren't so many buildings with any age to them. The central bit felt like a little town, and then the accommodation is on the outskirts. Lots of trees and nice spaces. Big arts centre that we didn't go in but it looks impressive, and the business school is massive.
We took a detour to see the separate campus for life sciences / medicine, can't remember who mentioned that being down a lane but there is a path for pedestrians and cyclists, through a nice little wooded bit. It is lit and is about 10 mins walk from the main campus.
