My dream vacation (Shoma)

I would like to go to Germany by a plane with my friends. There are two reasons why I would like to go to Germany. First, I studied German in university. I would like to talk with German. Second, I like old buildings. Especially I would like to go to　Neuschwanstein. This is famous beautiful castle in Germany. I would like to stay Germany as long as I can because there are many famous place in Germany. My dream vacation is going to Germany to go sightseeing. The reason why I choose sightseeing is that I would like to decide my travel plan. I will go to Germany next summer vacation.
