Has anyone here ridden from Vienna to Budapest (or vice versa)? I'm hoping to plan the route for the trip (which begins 8/31/11) beforehand, which gives me little time to order books or maps. I'd hoped to find detailed maps or GPX files on line, but I haven't found much yet. There's some information at openstreetmap.org but it seems to be mostly short fragments of routes, and in some cases multiple routes (e.g., between Bratislava and Budapest) with no explanation about which routes are suitable for cycling.
