Please respond if you have actually driven this part of Rome...

My family of three will be traveling from Sorrento to Rome. Cost of all three to use the Circumvensuvia (sp) to Naples and then to Rome termini and then taxi to De Le Ville is greater than simply renting a car for the day from Hertz in Sorrento and dropping it off in Rome. Plus, I think the hassles to changes train and taxi and deal with Naples is offset by driving in to Rome.

The dropoff in Rome is in Villa Borhese which is just afew blocks form the De La Ville. Question is how difficult is it to get to Villa Borghese from the A24?
