The ship docks right in the city - a big plus as you are on your way to sightseeing quickly. We used a private operator (Limo in Rome) that provided a minivan for our party of 6.
We traveled the Amalfi coast with stops in Positano and Sorrento, lunch right on the water in Sorrento and a stop in Pompeii. There were a lot of ships in port and in Pompeii. Many times we turned a corner we found yet another 2 - 3 large groups and there was sometimes a wait to go into various building.
There is so much to do in this city that one can only scratch the surface. We rented a van and driver from Limo in Rome for the day and had a private guide for 3 hours. we had not planned on the guide but the limo company provided him for free (we tipped well). It really enhanced our experience of ancient Rome. We went into the Coliseum and Forum and stopped at Aventine Hill, the Pantheon, Trevi Fountain and Piazza Navona. We purchased sandwiches and had the driver drop us in the Borghese Gardens for a picnic. What a quiet spot in a noisy city. We finished the day walking over Ponte Angelo and down to the exterior of the Vatican.
The driver was fantastic. Rome driving is a real challenge and he got us safely to where we wanted to go with only short walks to the attractions.
We rented a van and driver from Limo in Rome for our party of 6. Mauricio was very knowledgeable and were able to see Pisa and spend a few hours in Florence. The view from Piazza Michelangelo was beautiful.
When we mentioned wanting to see some of the countryside the driver offered to stop at a winery. We had a personal tour and tasting of wines, olive oil and specialty port products. The 10 euro fee was reasonable, but we were surprised by it. Suggest if you do personal tours you ask for the cost of any suggestion made by the driver.
This was our last port and we did not plan anything in advance. The pier was right in town and we caught the hop-on hop-off bus right outside the pier for 15 euros. There is not as much to see as in other ports, but the cathederal is worth a stop as is the overlook at Belvar castle. Our kids took the city bus to the catederal for 1 euro each and walked around the center city for several hours and back to the ship along the harbor walkway.
