Can't recall which thread it was in but someone was bemoaning the fact that there may likely never be this kind of club in the US.  In the same thread someone commented about attitudes not just in europe but in Latin American and Singapore.  I'm particularly interested in any elaboration that can be provided from personal experience in those two locales (Central/South America and Singapore - or other Asian ports of call).

Singapore: Orchard Towers. Not exactly FKK, in that the girls are dressed. But they are just as available. And the choice is much better -- there are 4 crowded floors of clubs to choose from.

Latin America: Start with "termas" in Rio (e.g. Monte Carlo, L'Uomo) or in Sao Paulo. These follow the FKK model pretty closely.

What does a party in Singapore or Brazil run???
