I'll be splitting a week between Dongguan, Shenzhen, and Macau very soon.  The majority of my time will be in Dongguan (likely the Sofitel hotel).  This will be my first time in China -- does anybody have any recommendations on quality places with quality talent?  I have some reservations on the cleanliness, grooming, and attractiveness of the women there (could be unfounded), so I'm doing my best to get a sense for the pitfalls that may exist in that regard.  I'm particularly in the market for overnight sessions, but only if the talent is worth it.

Ideally, I hope to avoid the fuss of wandering around, especially since my work schedule is pretty tight.  I'll also be traveling with a native Chinese coworker, who I'll ditch in the evenings, so discretion and efficiency are also important factors for me.

Thanks in advance!
