Hi, everyone. I'm going to be in Munich next month, and my girlfriend and I want to spend a day in Nuremberg. I went to buy our train tickets online, and learned that when we show our tickets, we'll have to show the credit card used to buy them. Third party tickets aren't allowed. Does this mean that we each have to buy our own tickets separately, with our own credit cards? Or can I buy both tickets, with my credit card, since we'll be traveling together?
