Visit Stratford
Stratford up on Avon is best visited by bus from the campus bus interchange to Leamington, then train from Leamington to Stratford.
Whilst there, you can visit Shakespeare's Birthplace, maybe take in a show at the world famous Royal Shakespeare Company, or try Tudor World, for a multimedia interpretation of Stratford in Tudor times.
If you want a little more up to date entertainment, how about The MAD Museum for displays of mechanical art and design, or just hit the shops!
