Just got back from Germany, and adored the trains. Everyone, including the passengers worked together to make the schedule on time by getting up, smartly grabbing their bags and getting off at the stop without loitering.

That said, the website for buying tickets was atrociously bad. We had a group of six and the website was full of bugs and broken for tickets with more than five people. You essentially have to do one ticket with 5 and one with 1.

We even went to the gate agent for help and they had similar problems.
