We're planning a trip by rail, Switzerland to Italy. Kids age 9 & 11. We're currently thinking Zurich, Lucerne, Interlaken, probably then Zurich to Milan, Florence, Pisa, Rome. We were originally thinking of going to Cinque Terre but have been put off by reading it's a line of people almost queuing up to see. Then we heard Rome is pushing through crowds to see say a fountain. To be honest although the kids say they want to see things like the leaning tower and the colosseum, I'm thinking it sounds a bit mad and perhaps not enjoyable. Is it any better in the winter?! Are there any nice towns we could go to in Italy instead, to have a more chilled experience? We'd like Italian food, gelato, scenery and architecture. Or alternatives to Italy, do-able by train? Or do we do more in Switzerland?
