Adult daughter and I have 2.5 days to spend in another city/area. Since it's a short time, we'd prefer a shortish (5 hours or less) train ride and direct flight. We've just been to Prague, Vienna, and Bratislava. Had hoped for Ljubljana but that appears to be a 9-hour train ride, and an even longer flight. I like natural beauty, but will be happy with an interesting city. Thanks for any ideas you can give me.
