Macau: are you interested in Sauna or pick-up?
Sauna are going to cost you; eg. HK$1200 to 1800/2000. The most famous sauna is in Golden Dragon Hotel across Sands. Variety of "gers" but mostly PRC.
Darling sauna at China City behind New Yaohan offers more Thais and Viets. About 1600 as i last recall.
Pick-up from Disco usually starts after 2 or 3am (as the gers get off sauna for side money), u can check out D2 at AIA tower, D3 at Fisherman's Wharf, MP3 at Macau "Lan Kwai Fong" or even MP4 at Royal Hotel.
D2 has mix of Russia, Thai and Viet but less FL now. D3 is most Thai and Mongolia. MP3 has filipino FL sitting around but not my type; and MP4 is mostly Russian. Price usually starts from HK$100 now and LT/ST depends on negotiation.
Wished i could share some FR on ZH and other area of China but no big fan of PRC so not bothered to remember. sorry.
HCMC:
I usually take-out from KTV especially from "Catwalk" beside New World Hotel and there is another joint under the same owner but can't recall name. LT is now US$200 and ST is US$150 (3 years ago was only $100 for LT ... geez).
There are couple of pick-up disco where girls would range from $80 and above but i can't recall the name. But if you want to see "decent" quality girls, check out Volcano disco. Can pick-up? depends on how sweet your mouth is
Actually most disco have FL roaming around, just keep your eyes "wide" open.
But be sure to stay at "ger" friendly hotel as 3 stars and above would not allow "ger" to enter to your room if not checked-in together. So best is to stay at motel and some will charge $10 for extra guest.
Anything else PM me.
BTW, u going Tokyo in Feb? Was planning a return trip (first trip was with my gf so cannot "cheong") as the gers there DAMN tempting man ... Make sure to check Shinjuku and Shibuya for action BUT have loads of cash. Just standing in a women's shopping mall in Shibuya 107 or 109 will bleed u to death. 7 to 10 floors of WOMEN shopping only ... check out all the baby dolls. I might join if u can confirm dates.
