I visited Naples and Positano in June and no way would I ever want to drive in either of them again.

Two couples will be taking the train out of Rome on Oct., headed to Naples and ultimately to Positano. We were considering renting a car in Naples, and driving the rest of the trip, and then keeping the car in Positano. But can we do without a car?
I forgot to ask - Why the train to Naples? After our 4 night stay in Rome, we (2 couples) went back to the airport to rent a car. I know airport extended stay hotels in new jersey rental fees are higher but it is easier to just get on the highway and start the journey than to try to navigate the city streets. Just make sure you rent a car that will accommodate 4 people and all of the luggage.
We were traveling in April/May and stayed in Positano 3 nights. Our plan was to take the boat to Capri for the day from Positano, but because of high winds, extended stay hotels in new jersey it couldn't dock that day and was only picking up in Sorrento. If we didn't have a car, we would have had to hire a driver to take us to Sorrento to catch the boat. Yes there are many, many steps on the Amalfi coast. We had 73 just from the street to our hotel room, but that's why the have the views they do.
We kept our rent car one day in the Amalfi coast after driving in from Sienna so we could go to Pompeii, then happily turned it in at Sorrento and took a bus back to Positano. We wouldn't have used it at all, as there's a bus to everything and parking is a pain in the neck and extremely expensive.
Horizontal: Yes, been there, and I understand. We're prepared for the steps. extended stay hotels in new jersey Also, the grocery store delivers. But we would want to walk into town. I don't see how having/not having a car changes anything about that.
We prefer to stay in Sorrento - with a car, the hotel has free parking - but we go in mid to late May when it's not really crowded yet. Drove to every place we wanted (except extended stay hotels in new jersey Capri obviously) with no problem - and frankly, I think public transit would have been a PIA for us.
I have been to the Amalfi coast many times and I would never want to rent a car there. Public transportation is very good (train between Naples and end of line at Sorrento), CITA buses everywhere else. Parking is a problem and a hassle with a rental. Who needs the stress? You can easily extended stay hotels in new jersey do all the places you mentioned and more by train and bus including Ravello. extended stay hotels in new jersey I like Sorrento for a base as it is easy to get to all the other places.
I visited Naples and Positano in June and no way would I ever want to drive in either of them again. Total hassle, limited parking, navigating through tiny streets or the Amalfi Coast Drive on the way to other towns/cities extended stay hotels in new jersey is not my idea of a good time.
It is not necessary at all. You have the SITA bus to take you up to Sorrento (where you can get the Circumvesuviana to Naples or Pompeii) or take the bus down to Amalfi and Salerno, where you could get the train to just about anywhere.
