How can you find out the better places to visit? There are different ways. If your friends have been there, you can talk to them. They may tell you a lot about the place. And they can also offer some useful advice. For example, which part is more interesting? How can you enjoy yourself better? What should you pay more attention to? The      
advice is all from their own experience.
       Another way is to consult a travel agency. The agents may offer you a lot of information. And they are always ready to help.
       Besides, you can also read travel books. Sometimes, they are better than a friend or a travel agency, because you can always read them whenever you want.
