Hi; Have you considered renting a car for three days. We have driven from Salzburg to Prague [about five hours], with a blocking in Chesky Krumlov. Many people do not like to tool along in Prague, but entering the megalopolis on the eastern side was not bad. Then it's four hours to Vienna and you could find a bring to a stop and sink the car off when entering Vienna. You would needfulness consent from you car rental associates to document the CR. For us, we simply try to pass into a diocese when we ponder it's off nib freight. Our last explode to Germany, I never wanted to split a car with GPS, but we received an upgrade and it was included. Gargantuan ease. A petty info. Richard For Prague www.inyourpocket.com
