The reason that I am writing to you is that I am going to take a one-week leave and I am planning for a vacation. I heard that you have recently taken a course for becoming a tour leader. Therefore, I think you definitely have much information about different attractive places that I can choose. As a result, I would be grateful if you could accompany me in this vacation.
