I will be renting a car for the first 9 days of my trip, switching to train for the last 4-5 days. (There will be 6 of us, so we found the car more cost-effective.) Our first train day will be on a Saturday, going from either Nuremberg or Frankfurt (depending on car drop-off) to Berlin. What is the deal on Saturday in-Germany tickets and do I need to purchase in advance?
Also, I am having trouble understanding the special buy tickets. I know that if you buy some tickets in advance, they are drastically reduced (like 39 euros instead of 109 for a fare.) How far in advance do these need to be purchased? What is the tactic for this?
I'm great at travelling in the US, but my Europe travelling skills are from the 80's and early 90's.
Thanks!
