Just found out that the official Wales Rally GB site has just put its online rally planner up - seems a lot better than previous years :)

Go to Wales Rally GB : Online Rally Planner (http://www.walesrallygb.com/308_376.php) then click your chosen stages on the right hand side. You'll get a stage location overview map, but you can click on each car park and see a coutoured (kind of 3D) map of each car park area and surrounding viewing.

Descriptions look pretty good too.
