I will be finishing some work stuff in Amsterdam and then head into Germany for 2 weeks of travel before ending in Berlin for a conference.
My first inclination was to take the train into Cologne, as that is the German city always mentioned as a day trip from Amsterdam. The idea was to arrive in Cologne, spend the day and night and then pick up the rental car the next morning.
However, as I was reading threads I saw someone mention Frankfurt. There appears to be a direct train that is about 4 hours long.
I don't know our itinerary, but I know we need to visit Nuremberg and Munich and then eventually get up to Berlin.
Would it make sense to skip directly to Frankfurt? That would save us some drive time (I imagined we would head to Frankfurt from cologne on the way south).
Yes, I know I would be missing cologne and the cathedral; however, I am ok with that since I know I'll be back in the region in the future.
