Has anyone done a day trip to the Naples area (Sorrento/Amalfi/Positano/Pompeii) while staying in Rome? We are planning a trip to Italy and would like to see the Amalfi Coast and do a relatively quick (2-hour?) tour of Pompeii, but we don't necessarily want to stay in that area overnight and take away from Rome, Venice, etc. I'm seeing on Tripadvisor that there are day tours you can book from Rome, bt that seems like a long drive there and back in a bus. Some others recommend just taking the train to Naples, which supposedly takes about 70 minutes and is reasonably priced, and then hiring a guide to drive us where we want to go. Has anyone done either of these options?
