The conference will be held in Portland Building, which is number 15 on this map.
The conference is taking place on the University of Nottingham's University Park Campus. Details of how to get to University Park can be found here.
If you require accommodation, there are various options. The closest accommodation is the Orchard Hotel, located at the East Midlands Conference Centre on the edge of the University Park campus, and about 15 minutes' walk from Highfield House. The university may also have rooms available in halls of residence on the University Park campus. About half a mile from campus, and (usually) rather cheaper than the Orchard Hotel, is the Wollaton Park Travelodge. The Experience Nottinghamshire website, in addition to providing a range of suggested free time activities in and around Nottingham (should you have a few spare hours before or after the conference), has information on booking accommodation in local bed & breakfasts, hotels and hostels.
