I've never taken a gal overnight in Macau, it just goes crazy on the pocket. The rule of thumb is 3xST = LT in most cases.
However, charm them enough and sometimes they'll just go up with your for a room with a view
Again, I've never partied like that before - frankly CP is a much better place to do something like that since the gals are somewhat less restricted by schedule. In Macau the hottest PRC gals are all tied up with Sauna and Visa Runs, and what you have are the FL walking the casino floors.
