Germany is one of the richest countries in the world. It has the largest economy in Europe and the fourth largest economy in the world. Thus said, it is unlikely that you are going to encounter a lot of problems getting around the country. However, you may need to consider the following factors before you set sail to 'Deutschland'.
1. Do you need a Visa?
For the US citizens that do not intend to stay in the country for more than 90 days, a valid US passport will suffice. If you are staying longer, then you will need a Visa. Citizens of the European Union do not need a German visa to travel through/in the country. People from all the other parts of the world will need a valid German Visa to get into the country.
2. What is the best time to travel?
For those who love the sun, sorry, you will be competing for space with a lot of other people. The advantage of travelling to Germany during the winter months is that you find that the hotels are heavily discounted to attract customers. Besides, it is the best time to enjoy some winter sports such as skiing.
3. Where do you want to go?
Germany is big and all the cities may seem overwhelming for the first timer. But a comprehensive look at what each city has to offer can help you make the decision faster. For example, if you love the nightlife, no German city beats Berlin. If you are more into making business deals, you stand a better chance in Frankfurt.
4. The Language Barrier
Gone are the days we could not travel to a foreign country just because we do not speak their language. Today, there are hundreds of apps that translate any language into English. Still, if you feel you need to communicate more in the local language, you will need to attend some German classes - this costs money, money which should be in your budget.
Your budget will determine where you stay, how you get around, which city you visit, what type of activities you engage in and many more. For example, you may want to get around in a chauffeur driven car but after analyzing your budget, you settle on travelling around with a group of tourists since this is cheaper.
There are several other factors that you need to consider, but I guess I have highlighted the most important. Make sure you have a concrete plan of how you are going to spend your time in Germany - you do not want to get bored halfway your vacation, do you?
