If you want to be able to make your own sentences and be able to express most things you want to say on your trip, then yes, the course is for you. The first part of the course covers everything you need to know to reach a good, basic German - including asking questions, giving and understanding directions, reserving a room, understanding a German menu and so many more things. It corresponds to level A1 of the common European framework and covers the most important parts of grammar you will ever need in the German language.
However, there is work involved. It is not one of these courses which teach you sentences to say in different situations and that you should learn by heart. In that type of courses, you might be able to quickly pick up some phrases that will be useful on your trip, but they won't give you the power of creating your own sentences and you probably won't understand what people answer back.
So, it depends on the level of understanding and autonomy you want to reach and the time that you can invest for learning. If you are looking for a course that teaches you "yes", "no", "where is the toilet?" kind of phrases and only want to invest two or three hours of learning, this course is not for you. But if you want to understand the underlying structure of the language so that you can actually make your own sentences and even go a bit further, then it will be perfect for you. For each level, you will have to invest about 35 hours for my videos and some additional time for homework and review. And who knows, you might like it so much that you just keep learning until you speak it fluently 🙂
