Most amazing tour ever: sitting behind a guy on a vintage Vespa while touring the Amalfi Coast in one day! It was just me and my husband, plus our two drivers and the car that followed us (we were picked up from our hotel in Naples). Saw everything, got to shop, get coffee, lunch (not touristy), historical sites. Can't get stuck in traffic on a motorcycle! We booked on Viator, but you can book direct from their website: http://www.napolinvespa.it/
In Naples, near the Spanish Quarter, best coffee & desserts & gelato: Gran Caffe Gambrinus.
