John,Interesting question- living in Angeles City must be kinda like living in Willy Wonka's Chocolate Factory- immediate gratification abounds everywhere. But I would think that if you were going to go somewhere else, it would be for other activities than mongering...
It's difficult to stereotype about looks- I find Javanese women very attractive, and yes, they typically are darker, like many filipinas. You can certainly find youthful, pretty and naturally fit girls in Jakarta. You'll also find short ones, fat ones, skinny ones, pale ones- I'll post some pictures when I get back to my home computer.
To me the biggest difference from somewhere like Angeles is that Jakarta is a very big city, with a huge variety of experience, from high end spas to dive bars. However, you won't get public performances like gogo bars, because it's a muslim country. But there are a huge number of working girls in Jakarta- just as a WAG, I'd think 10 times as many as Angeles (but I'd certainly defer to other members of the board who have a more scientific methodology)...
I didn't find Stadium a particularly good forum to find girls. If you are going to go to a spa, then Alexis if you have a high budget, or the 6th floor of Malioboro for mid tier, or Hotel Travel for cheaper. All are nice establishments with clean rooms. For overnight take home, yes Blok M works well, and I've always found something good at Top Gun or D's...
Does Jakarta offer something not available in Angeles? Well in the end, like they say in Thailand, it's the same-same, but different. Is it different enough to warrant buying tickets to Indonesia? I dunno- that really depends on how much it costs, and how much you want to get out of AC. All I can say is that I've always enjoyed my visits to Jakarta, and I went 6 times last year (though 3 were not mongering trips)...
