Germany - Tips

You are trying to do too much n 11 days.
If you are just visiting these cities, you don't need a car. Use the train.
If you get a car, get a GPS

Since all the cities mentioned are connected by frequent fast rail service, a car is going to slow you down. Plus you pay a big fee to rent a car in Berlin and drop it in Vienna. A car in Munich is a head ache, probably in Vienna as well.
You are trying to cover too much, but to speed things up, you might try doing Dresden and Salzburg as 6 hour stopovers between Berlin and Nuremberg, and Munich and Vienna. You can build these in using the stopover function on www.bahn.com.

If you will be driving on the highways in Austria - and to go where you want to go, you will be - you will need to purchase a Vignette as you approach the border. It costs around €10 for 10 days for a car, and is a tax for using the motorways. It must be stuck to the right place on the windscreen. Fines are large and immediate if it is not on the car before you cross the border.

Austria requires that all drivers (with exceptions for holders of driving licenses from other EU countries) not only have their home driving license but also an IDP - International Driving Permit. I don't know where those are available in Brazil; in North America they are available with photo for less than $20US at the Automobile Association

You may not be required to show the IDP when renting a car, but if you have an incident you will need it. You need to have it before you leave Brazil.

I agree, you will be covering a LOT of ground in the time you have.

If you are travelling trans-Atlantic, use a multi-city search function to fly into one German city and out of another, or Vienna. Saves time and perhaps even money. Berlin has relatively few direct flights from the American hemisphere, considering the city's importance, and I suspect the same is true of Vienna. So a connection in a gateway such as Amsterdam is to be expected.

Hi Eduardo,

11 days. Is that 10 nights or 12 nights?
11 days total or 11 days after leaving Berlin?

Cars in Munich and Vienna...don't do, just don't. It isn't worth the hassle or the cost.

Thank for all comments. This is a first time to we are making by myself this kind of trip and everything is new and a little different from Brazil - this is the intention as well.

I will continuing my researches.

I question what you mean by 11 days. People often count the arrival day, which won't be a full day and will be largely wasted due to jet lag, and the departure day. Most departures for the US are early in the day and so most of the Europe time is spent just getting to the airport.

You are spending three "days" in Berlin, so you'll have some time in addition to the arrival day, but you're planning five more venues in the next eight days (maybe seven plus the departure day). It doesn't take a full day to travel between any of those cities, but by the time you check out, travel, and check in, it'll take more time than you thought, and you'll only have one full day in two of those cities.

Eduardo,

As the others have mentioned, travel by train would be far easier than by car. The high speed trains travel at up to 300 km/h, so that's much faster than a car, and a much more efficient use of your very limited travel time. Travel by train also means you won't have to be concerned with having an International Driver's Permit or buying Vignettes for driving in Austria (hefty fines if you're caught without the Vignette). You also won't have to worry about parking, speed traps or other issues like that. Using a car within cities is NOT a good idea!

You can research trips just about anywhere in Europe using the German rail website - https://www.bahn.com/i/view/USA/en/index.shtml

You can buy tickets for rail trips originating in Germany at www.captaintrain.com (they don't handle tickets for Austrian rail yet).

Are you using a guidebook to plan your sightseeing in Germany?

I agree with the others in that you have too many cities for a short 11-day time frame. Keep in mind that you have to allow time for travel between cities, which will usually be at least four hours in each case, as Lee pointed out. It would help to have more details on your plans. For example, is 11-days your actual time "on the ground" in Europe?
