The University of Sussex offers a list of approved hotels and guest houses here. The university campus, where the conference will take place, is a brief train or bus journey from Brighton, where a range of accommodation can be found.
The conference will begin around 9.30am. After McKenzie Wark's keynote address at the end of the day, speakers and attendees are invited to come to dinner in Brighton at around 8pm. (Dinner is not covered by the registration fee, though we will head somewhere reasonably priced).
