We just returned from a cruise on Celebrity's Edge and booked this tour through ItalyTours.EU. Our driver, Salvatore, was funny, conscientious, and gave a great amount of information as we made our way from port to Positano, Sorrento, and Pompeii. Glad we did the stops in that order as there was a MASSIVE traffic jam in one of the tunnels headed away from the port as we were returning.
Before we reached Positano we stopped at a roadside stand for some fresh squeezed orange juice with lemon sorbet (yum!) and many photo opportunities. When we arrived in Positano, Sal parked at a garage/lot and pointed us in the direction of a number of shops and the seashore. After our free time there, we headed back towards Sorrento, where Sal again came through with a recommendation for a spot (Aurora) to get some lunch. Stuffed to the gills, we walked around a bit to burn off some of the calories, then it was off to Pompeii where we met our tour guide Erica. She led us through the site and gave us great insights as to the history of the city. Finally we returned to meet up with Sal and head back to the port in Naples. I would HIGHLY recommend this tour, and be sure to include the guide in Pompeii! It was a busy day, with a lot of walking, but thoroughly enjoyed by all our group.
