There are several options how to get to Cambridge.
The college is located in the centre of Cambridge. They provide a useful map and directions, but you will probably want to find your accommodation first.
Accommodation is not included in the workshop fee. A good list of accommodation is provided at http://www.smoothhound.co.uk/cambridg.html.
The college has a limited amount of accommodation available for delegates; it will be possible to book this once invitations to the workshop are issued at the end of January.
