The Amalfi Coast is like another world-- in about a million ways. Buses come and go as they please, restaurants and shops operate on their own agendas, and locals carry on as if nothing has changed. There seems to be no rhyme or reason for anything south of Rome.
Admittedly, there were hiccups. When you depend on public transport and all lines are unpredictable, you can't make plans. It took a while to get to this point, but the coast is best when you let go of your schedule, find a secluded inlet, and let the Mediterranean waves guide you instead.
