So, in less than a month my wife and I will be touring Paris. From Paris we'll be taking the train down to Provence. I've heard the Paris - Avignon trip can fill up quickly. So, as soon as we get to Europe, I'd like to book our reservations on the TGV. Also, we're taking the night train from Nice to Venice.
Can we book our reservations from ANY train station (such as Centraal Station in Amsterdam when we arrive in A'dam)? And, are there any tips / things to be aware of when taking the night train--neither of us has done it before.
