I love this forum and how helpful other travelers are when planning trips. We did a 12 day tour of Italy during the first two weeks of October 2022. Flying into Venice (3 days), onto Florence (3 days) with a day trip to Pisa and Cinque Terre (took the express train to all 5 villages with no daylight to spare), then to Amalfi for 2 very warm days on the coast, finally we hit Pompeii before our last 3 days in Rome. The trains give excellent mobility throughout this beautiful country and this was my first trip to Italy where I booked every single thing before we left the US. The weather was perfect, and every step of the journey worked out perfectly. We saw all the tourist spots in each city along with extras along the way. The only time we saw rain was during our 3 hour train ride from Florence to Naples/Amalfi. The only question I have now is, where do we go for October 2023? :)
