I ventured to Europe the summer before I went to college, I went with two of my really good friends, none of us wanted to come back by the end of the trip. It was great we spent two weeks in Amsterdam, unbelieveable.

Although I had a great time, I dont know if I would advise going by yourself, it would get kind of lonely. If you are going to visit something, walking around by yourself just isnt fun in a country where you dont know the language or have no knowledge of the place.
