As of the lack of knowledge of TA's here, I became my own travel agent. Most luxury hotels can be booked online on their own websites. The rate is more or less equal to what the TA's could ever offer me. Or you can always use pages such as expedia, hrs.de, aisarooms...
I normally check the hotels I am interested in on tripadvisor, and then shop around online for the cheapest rate.
For flights, try zuji.com or the airlines webpages. Some, such as LH, will offer you the possibility to book multi stop tickets online. Otherwise, call them and ask the agents to give you a quote for booking.
I know, this takes a bit of time, but I always came up cheaper than with the packages the TA's offered. What I find especially annoying with HKG TA is that they don't inform you on limited a/v of airline seat. Once the agent told me to pay first, then he would try to book the airticket. Nice try...
