As Manchester is unusually busy during the weekend June 29th/July 1st (thanks to a Stone Roses reunion/comeback gig in Manchester, for which over 200,000 tickets were sold), we suggest you book your accommodation early and consider the (new built, conveniently located) student hall and the hotels recommended on the IJCAR 2012 accommodation site.
IJCAR will take place at the School of Computer Science, University of Manchester
in Kilburn building (building 39 on the campus map), just south of Manchester city center. Oxford Road station is the closest train station, Piccadily station is a bit further away. George Kenyon Hall (suggested accommodation) is building number 93 on the campus map.
Please take a look at the map of IJCAR-relevant locations.
