Brussels

I lived in Europe for many years and still occasionally travel there, usually to Belgium and Italy. I agree with all earlier posts with one addition. At train and subway stations, especially later in the evening, there are not always employees available to sell tickets at every station. In those cases, having a Chip & PIN card is really beneficial. (A Barclay Aviator is my Chip & PIN backup, with CSR being my first choice.) In my experience, sometime human attendants are absent late at night at service stations in Germany and Belgium. Unattended automated parking lots, especially late at night, can also present a challenge to those traveling with only a signature card. Again, a Chip & PIN card deals with these issues nicely.
