It's been a long time since I've been there.... but enjoyed it, regularly, for over two years, back in the 90's! I have always said Singapore has more great looking, exotic women, than
any other place I have ever been to. It is an international melting pot!!
Shortly after arriving in my room.... Business Cards would appear, slid under my door.... probably left by Hotel Staff, working in conjunction with some of the higher end girls. I partook, several times, via that method.
Back in those days, there were several clubs in which working girls were casually available. If you Google Singapore Escorts... you'll get a ton of info.... but you might want to try
http://worldsexguide.com for advice & reviews.
Overall.... back in those days.... Singapore was a very safe place to enjoy the hobby! My suggestion, would be to ask your cab driver, on your way from the airport to your hotel.
Enjoy.... and be sure to report back!
