We are going to be on the Amalfi Coast for approximately 4 days in May. Probably staying in Ravello (although open to other suggestions). We do not want to drive ourselves and we definitely want to go to Herculaneum, Pompeii and Paestum. Suggestions on private driving/tour services? Thanks so much.
I was very happy with Aldo Limos. Safe driver, very courteous. We used them this April for a pickup at the Naples train station, drive to Herculaneum, stop while we toured and then drive us to Positano. http://www.aldolimos.com
We used Simply Amalfi: http://www.simplyamalfi.com in September of this year. They picked us up at the Naples train station and drove us to Positano and picked us up a week later. They are courteous and very dependable. We only used them for transfer but they gave us amazing local information in route and also offer tours. They were recommended to us by a neighbor who had used them for a full day tour of the Amalfi coast. They will respond to your inquiries very promptly.
You could also try one of the services listed in the guidebook, http://www.monettitaxi17.it/English.htm (I assume it's still in the book, although I haven't checked lately).
I used Aldo Limos, based in Sorrento, twice on an Amalfi visit a few years ago, and got excellent service.
We used Sorrento Silver Star and were very happy. They picked us up in Atrani and drove us to Ravello/Sorrento/Positano - but you can tailor it to what you want to do...
