My wife and I have been to Europe once before (Madrid & Rome) and loved it. She found some good airfare for a trip in April to Germany so we're going to book one. My question is, which of the three places listed below should we go?! We're planning on spending 6 days total.
Dusseldorf - Do stuff there then take a train to either Cologne, Germany or else to Amsterdam
Munich - Do stuff there then take train to Austria?
Berlin - Do stuff there and not sure where we can get by train
Anyone have experience with any or all of these places? We probably wont go back to Germany for a very long time so we want to get the full experience in the short time we'll be there. Ideally we would like to go to another place nearby as well. We would have to still come back to our original destination though, since we're getting round-trip flights from one of those places.
Other things worth mentioning:
1) We're 29 and in good shape - willing to do anything physical. I'd prefer outdoor activities but that's not a must at all.. we're just going there to get the full experience of another culture
2) I know the trip wont be cheap, but I still want to keep an eye on the budget so less expensive things to do would be ideal.
I've been to all the places you mentioned, but I have the advantage of having my friends (Germans) drag me around to wherever they go. During the day, I am taken to some of the "necessary tourist" spots, and at evening/night, I'm just another one in the group.
Cologne is nice (The Dom is amazing), but the town/area gets small quickly. You could really cover the town/area in a couple days.
Munich is awesome. Bavaria is ridiculously clean in general, but Munich is spotless. If you end up in Munich, you must make time for a trip to Regensburg. Amazing city with awesome history/culture/nightlife.
If you're in Berlin, you won't need a car since the public transit is so good. The history/museums/culture/nightlife is great. In my experience, speaking English is not a problem anywhere in Germany, but Berlin will be the best place for someone who knows zero German. FYI: There is a train that starts in Berlin and ends in Amsterdam.
PM me if you have any other questions.
