I am planning to purchase a Swiss Card. I will be traveling from Beaune, France to the Berner Oberland. I would like to purchase my ticket for Beaune to Basel now, before the TGV prices increase. Am I right to do that, and then when we get off at the border town of Basel to switch trains, get the next ticket to the final destination using the Swiss Card? Or would I even need to get a ticket, is the Card enough (in this case the trip will be covered by the Card)? Thanks!
