I've been to the Czech Republic and, not to dog the country, but there's more to see and do right around where your daughter is at. Garmisch is a resort, Munich, Neuschwanstein castle, the Alps, the Eagles Nest and Austria are all right there. The Euro is expensive so I'd stick around where your at instead of going to Prague. Germany is a beautiful country, enjoy your trip, wish I was going.
Have a beer for me.
