Booked a nice looking hotel in Amalfi proper. Planning to do the train to Salerno then ferry to Amalfi as suggested above, and then my hotel offered a transfer from Amalfi to Naples airport for 100 euros which seems reasonable enough.

So we will have a half day and 2 full days there. Thinking Amalfi for the half day, Positano for a day, and maybe Pompeii / Herculaneum for a day. Would also like to see Capri but not sure how to fit all that into the few days.

Any suggestions on which of those sights / towns to prioritize?

(and PM sent re: the driver recommendation, thanks!)
