This is more of a question you have to think about yourself, where have you always wanted to go and visit?
Why did you want to go and visit that place? Was it because of some big attraction there, certain landmarks, or just to go sightseeing?
Personally, I've always wanted to go to China. The mythological culture surrounding it has captured my imagination since I was young. Some of the really cool everyday technological advancements here come from China. Not to mention all the different types of food that originated from there; Sushi, spring rolls, sweet pork, fried rice, etc. Seeing the Great Wall of China, or the tomb soldiers of Emporer Qinshihuang would be the top things on my list to go see, along with the giant pandas!
List off the things you would want to experience in another country, and expand on the main topics to get to your 200 words.
