Ok, we like to be adventurous. How do I get info on abbeys, convents, monasteries and castles that have sleeping accomodations? Googling has not been particularly successful. We are looking for something near Wurzburg, Germany area, near Fussen, Germany area, then in southeastern Switzerland near the Italian border. Know of anything? Or how to find out about these?
This may or may not help, but try asking the Spanish Paradores. Perhaps they can direct you to something in Germany. Best of luck.
Try these websites to find castles.
