My mother and father in law are flying into Berlin Sept 23 in the morning. They will be in Berlin for 6 days.
They leave on Sept 29 to join my wife and I in Koblenz.
In Koblenz we will rent a car together for 4 days for some site seeing in the area.
After we drop the car off we will take a train from Koblenz to Bacharach.
Then on the Oct 4th we travel together from Bacharach to Leipzig.
So, they have 6 days of inner city travel in Berlin.
And, they have 4 days of city to city travel.
I understand the flexipass is good for city to city travel. We got the any 5 days in a month for ourselves and are looking at the same for them also.
However, I'm not sure what mode of transportation is best for them in Berlin. And what kind of ticket they should get.
