A fundamental skill travelers have to develop is the ability to get around efficiently and economically using public transit. Here are a few train and city bus tips grabbed in a stream-of-consciousness way while zipping from the train station in Verona out to the street to catch my bus to the center (and my hotel).
Time and money are both limited resources. As you'll see here, you'll save time by getting adept at using automated ticket machines, and you'll save money (while losing very little time) by hopping on the bus rather than catching a cab upon arrival. While you won't always connect this quickly with a bus, you'll find most cities coordinate their train and bus systems pretty efficiently for those who make the effort to figure it out.
