I just read this guide: www.wikiadult.org/wiki/Zurich and no my dream trip would be to fly go Zürich, Switzerland. Only minus about the place is that is crazy expensive.
Good things are the following.
-You only have to drive under one hour if you want to snowboard.
-Smoking culture is not as open as in Amsterdam, but very open.
-Girls are very beautiful and easy to approach.
-There are legal brothels.
