Does the All Day Amalfi Coast bus ticket on Sita mentioned by Rick include the bus from Amalfi to Ravello or is that a different bus line?
It does, or, when boarding it at the end of the route area, and in Ravello, have never been asked for an additional ticket to use the bus to/from Ravello.
Yes it does. It also gives you a one way trip (out or return) on the open-top bus which runs between Amalfi and Ravello. The return/other part of the journey is done on the ordinary bus.
