Kaleu - I was in Macau a week or so ago, and knew I might be back around CNY, so I asked a few of the sauna girls what it was like at that time.
About 1/2 the PRC girls and 1/3 of the Viet girls I spoke to in the saunas said they would be away around CNY (and therefore, of course, that I should not come at all at that time
)
I asked whether it was busy during that time so that they'd lose a lot of business by being away, the answer was no, it's slow during that time.
So on balance, while there will be less selection, this will be offset by there being less punters doing the selecting.
My next HK/Macau trip looks like it will start around Feb 21 (yaay), 11 days after CNY, so I'm hoping to avoid the doldrums. But probably like you, it's not like I really get to choose the timing, so it is what it is.
