Don't restrict yourself to one area. Go through the 141 database and pick out the girls you like. Taxis in HK are plentiful and not expensive.
If you're in TST - Jordan and Yau Ma Tei are very close. Even Mong Kok and Prince Edward are in easy range - and the further you go from
TST, the less you have to pay for the girls.
Enjoy your stay in Hong Kong, be adventurous and get out of touristy TST. Every
whoremonger should experience the infamous Mong Kok
. If the cops and property developers have their way - it might not exist a
few years from now
. Cheers
