This sounded like a great idea but in truth, the river is very wide and the ship travels in the center. So, you see very, very little.
My wife was bored to tears most of the way. And when we got to Vienna there were no taxis at the dock. Not one.
We had to walk quite a ways to a street (dragging our luggage). Very few taxis going by; we got lucky and caught one.
In retrospect, we should have taken the train to Vienna.Edited: 08 January 2010, 21:24
