We are flying into Rome (FCO I believe) and need to get to Marina di Camerota. Looking for advice since it's a long drive and traffic in August will be heavy. How easy is it to get there by train? We're fine even if we can only get as far as Naples by train and rent a car there, although I'd like to get as far south as we can and then still be able to rent a car for the week we're in Marina di Camerota.
