Flying into Naples, spending 1wk in Sorrento to visit all the sites & Am.coast
then 4days in Rome. We would like to spend 4 days elsewhere before flying home fron Naples. Do not want to venture too far..somewhere scenic & relaxing would consider renting a car.
See my answer in the other place you posted this.
I'd take the train to florence...from there you can take a day trip to venice or a wine tour...and florence is beautiful itself
