Here is a map of official conference hotels and a link to download the KML file into Google Earth.
I’m somewhat disappointed by the display of the KML file through the Google Maps API. The KML file contains <address> tags, which in the Google Earth desktop application appears to enable the “Directions From” and “Directions To” options. It is entirely possible that I’m missing something in the KML file — it was created by exporting a folder of placemarks from the Google Earth application. The raw KML file, suitable for importing into Google Earth, can be downloaded from the link under the map.
