Hi Patrice,
Thank you so much for reaching out on Italiapass! This sounds like a lovely itinerary. Based on proximity to one another, the best order to visit these destinations would be as follows: Turin, Lucca, Bologna, Venice, then Rome. You can book rail tickets for each of these trips individually on Italiarail.com28. By booking tickets individually, you have the benefit of being able to choose your desired class of service and departure time/date down to the hour for each train trip. A pass may also be beneficial if you know you will be travelling for a fixed number of days throughout the country. However, passes don't allow for as much flexibility with classes of service. At the moment, italiarail is not offering railpasses. These can be purchased on eurail.com31.
At the moment, the train schedules have not yet been released for next year. I would recommend looking the current schedules to assist in planning. I am not sure when specifically you are planning to travel, but train schedules are typically guaranteed 60-90 days before the travel date.
If you have any questions or concerns regarding your travel planning and booking, do not hesitate to reach out to us directly at 1 877 375 7245 or info@italiarail.com89.
