Couldn't agree more with KL, got to visit a few times last year through work and loved it. Alas am back to projects in the Magic Kingdom (Saudi) this year but have great memories of KL and of Traders - the window booths in the sky bar are particularly cool - was always a little worried I'd end up in the pool though!

PS. As you asked......I'd have gone to Jakarta, but then again I'm (reasonably) young and impetuous and probably a tad laissez-faire with regard to personal safety.
