As per my previous note under "Discussions", for whatever reason they are no longer advertising on CityXGuide, and sent me a cryptic note:: "we are going back home".
However I can report the following: yes, as the others mentioned above, most are older and YMMV; however, the last was a tattooed Chinese about late 20s, spoke not a word of English, but was about as much fun as you could possibly have. I was hoping she might still be around, but when I inquired. Received the above information.
