Here is a map of official conference hotels and a link to download the KML file into Google Earth.
ALA Midwinter 2008 Hotel KML Location file
I'm somewhat disappointed by the display of the KML file through the Google Maps API. The KML file contains 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.
If you have any suggestions for improving the output, let me know.
