The workshop will be held in the Informatics Forum at the University of Edinburgh. Edinburgh has an international airport, and there are good transport connections. Local maps to the Forum.
July is a good time to visit Scotland, as the arts festival season starts late July, and the Commonwealth games will be held in Glasgow. See calendar for further details.
Limited accommodation for speakers and some students/postdocs has been reserved within the University Pollock Halls of residence. For those reserving their own accommodation, this University page has useful links. Otherwise, there are many hotels to choose from.
