Some other sites required tickets to be booked 7 days in advance, but the top link seemed to work for today as well.
I don't know much about Paris, but if you are taking a TGV (Shinkansen of France), then you would have to go to a major station somewhere there.
You may change trains in Italy. Just be careful there, because the train time is often not on time, and some trains have the same destination and leave at the same time. The difference is that one is a local train, the other express...
I tried the web site, but seems like the tickets for night trains are not available on the internet.
I dont'have any ticket from Paris to Rome & only have an air ticket from Rome to Japan. So, I'm a bit worry about when I enter France. Should be no problem. right?
Nice? If I have time, I might go. Thank you! (^^*)
