My experience is that the FKK clubs are relatively inexpensive, compared with what we've come to expect here. Last year I visited one in Frankfurt. I spent 100DM to get in and 100DM each on two girls. So for under $200 I had a great time! As I understand it, if you ask at most news kiosks at the main train station in each city in Germany, they'll sell you an adult entertainment map with listings of legal establishments. Some of the FKK clubs are listed on the net -- just do a search for "FKK Club" (be careful, because FKK alone simply refers to the nudist movement in Germany and I imagine most board members wouldn't be too interested in spending an evening at a nudist colony when they meant to spend it at a club). These clubs are usually located just outside of the city, but with public transportation as good as it is in Germany, you can usually get to them quickly, easily and inexpensively. It helps to know a little German.
