Staying in Revello on the Amalfi Coast. We will not have a car. Looking to get to Pompeii without breaking the bank.
Sita Bus from Amalfi to Meta di Sorrento, then Circumvesuviana train to Pompei-Villa dei Misteri. And the bank will be intact.
I think you could take a SITA bus from Ravello (note spelling) to Vietri Sul Mar then a regional train to Pompei.
From there it is a 20 min walk or quick cab ride to Pompeii Scavi.
