My fried lives in Stuttgart, and I live in a small village called Isny im Allgäu. We are planning to travel to Konstanz together. The problem is that there is no train in my village, so I need to take two buses to reach Ravensburg city. I can wait for him to get in the train with him.
The question is while he's coming from Stuttgart, can I use the ticket which is already for two passengers to get to Ravensburg city, because the train goes from Stuttgart to Friedrichshafen through Ravensburg?
