Hi, We will have 10 days ( coming from Chicago) and wonder if we can enjoy a few days in Paris and maybe a daytrip to Giverney and then take a bus or train (any high speed ones?) to the Amalfi Coast for the rest of the time and fly back from Naples or Rome. We are a young 60ish couple and very active - enjoy biking, hiking and just hanging out. We love nature and exploring cities. We have been to Paris before, but never to the Amalfi Coast. Is this too much for 10 days?
