I am traveling with 3 other females to the Amalfi coast w/ the intent on going to Pompeii, Capri, Ravello and of course taking the Amalfi coast drive. We are split on which city to stay in for convenience and getting around. Are they both equally as accessible by bus and boats? We will not have a car and we are flying in and out of Rome.Any advice?
Sorrento would be the more convenient base, as it has more transportation options. Positano is great and does fit well with your itinerary, but is about an additional hour of travel time from Rome or Pompeii. If going during season, you can take boats from Positano directly to Capri and Amalfi (close to Ravello). If going off season, you would need to go to Sorrento to get a boat to Capri.
In addition to Frank's comment, you get the jet boats to and from Capri from Sorrento.
Can you tell me how to get to Positano from the Rome airport and about how long it will take?
Because there are 4 of you, there are 2 options from airport to Roma Termini station that cost about the same - taxi at fixed rate of EUR 40 (plus tip) or Leonardo Express train at EUR 11 each. From Roma Termini, take a train to Naples. In Naples, you'll have 2 options. Arrange a car directly to Positano through your hotel - cost will be about EUR 100. Or transfer to the Circumvesuviana train to Sorrento and then to bus to Positano - probably about EUR 25 for 4 people. If you take the bus, ask your hotel which stop you should get off at. Most hotels are closer to the 2nd stop, which is at the bottom of town. Allow at least 5 hours for the trip, but it could be more like 6 hours depending on which train you take to Naples and connection times. Car service to Positano would likely be faster than Circumvesuviana and bus (about 2 hours).
