Hello,
4 of us will be doing a 3 week trip in Europe next May and using the trains to get around. On a direct route I see some trains need seat reservations and some do not, while the travel time is the same. Is there an advantage to the trains that have seat reservations vs the ones that do not? One example I looked at the seat reservations were about $65 each. I attached a picture as an example. We will be getting a 1st class global ticket. Thanks!!!
