Thanks Kent I wasn't trying to persuaded you, because I know everyone has had their experiences good and bad, and I hope that I can only learn from what others have done. I know since my last trip in May 06 being my first trip to Europe I learned so much and I really only want to pass on the information if I think it will help others!
David, our family came to the similiar conclusion as you did, we are picking our car up in Rome driving to Sorrento and then spending 5 days exploring the area before heading to Naples for a flight to Venice. My biggest issue in planning this trip was dealing with a "high maintence" mother... lol The other 1 1/2 of my trip I wil be alone and can use public transit and trains easy on my own, but with two parents in their 50's who just want to relax, a car straight from Rome to Sorrento I think will be easier than two trains.. as I have not heard great things about the circumvesa from Naples to Sorrento. Our car is small, a 4 door smart car, very cute
