This summer I'm planning to bring my family to Italy for their first time. Previously I visited Rome, Florence, Cinque Terre, and Venice. My brother and I are in our 20's and our parents are in their late 50's. Here is a tentative itinerary I have planned. I would love any feedback regarding the route/destinations I'm considering since I've never planned a trip for an older group.
Day 1: Travel from US
Day 2: Arrive around 9 am in Rome. Rome (Colosseum, Roman Forum, Mammertine Prison)
Day 3: Rome (Campo de Fiori, Pantheon, Trevvi Fountain, Spanish Steppes, Piazza Navona)
Day 4: Rome (Vatican City, Trastavere)
Day 5: Travel to Florence
Day 6: Florence
Day 7: Travel to Cinque Terre
Day 8: Cinque Terre
Day 9: Travel to Venice
Day 10: Venice
Day 11: Travel to Lake Como
Day 12: Lake Como
Day 13: Travel to Murren, Switzerland
Day 14: Switzerland
Day 15: Switzerland
Day 16: Switzerland
Day 17: Travel from Switzerland to US
I've visited Cinque Terre and loved it, however I've been told that for an older audience, spending more time in another location or briefly visiting Positano and the Amalfi Coast or exploring the hill towns of Tuscany might be a better fit.
Is there a better route to order these cities? I know there is a high speed train from Rome to Florence to Venice and regardless, Cinque Terre is somewhat inconvenient to travel to.
Thank you in advance for your help!
