It is possible that London College of Communications accommodation may become available. If so this will be announced on the website and via the EVA mail list.
Transport to the London College of Communications is excellent, so hotels north of the river will be as convenient as those on the south bank.
An excellent streetmap service is http://www.streetmap.co.uk
Google Maps misses out occasional streets and even some rail stations.
www.london-se1.co.uk/areas/southbank.html - information about the area, but the
hotels link is not very helpful

Many hotels listed, mostly to the east, Bermondsey etc, but buses to the Elephant & Castle should be plentiful
