Hello,
thank you for your question. You can go on our site at www.italiarail.com21 and enter the destination, which would be Milan to Paris and then the date of your travel and the number of passengers. The site will walk you through the booking process and allow you to choose the type of car that you wish to travel in. Depending on the date that you book if your route is showing unavailable you may wish to wait and try again. Train schedules are usually released 60-120 days before departure. If you still are unable to complete your booking you can send us an email at info@italiarail.com8 or call toll-free: 1 (877) 375-7245.
