I did a Prague - Frankfurt trip bout year and a half ago..  Did not partake in the Prague FKKs however did so in Frankfurt..    I preferred the FKK experience over individual Prague escorts.  If I could have hooked up with Terry Nova I may have thought different..

Did some recent research on return to Europe fuck fest this spring and from what I found it appears you get more bang for your buck at a German FKK..  So I'm planning a return trip later this spring..
