We did a long day trip out of Naples on our NCL cruise to first the Amalfi Coast and then on to Pompeii.  It was our first time seeing whole towns built into the sides of the shear mountainside and the views were just amazing. It would be hard to imagine ever getting spoiled by the views, even if you lived there.   The roads are pretty tight so the buses can only go in one direction, basically north to south along the coast and then they come back up the center of the country.
