If you go to a major Macau Sauna (East, 18, Rio, FN, Sanado, Boss), be prepared to spend 1/2 your budget in return for several hours of fun plus one boom boom and perhaps one other release. You can spend most of the other half on a double at Darling 1 if you like
If you want to maximize time spent doing boom boom, ignore Macau completely and stick to the many reviewed HK 141's or hotel girls.
If the bar scene is your preference, I can't help you -- not my scene.
For an awesome pampering experience with many friendly girls, spread over several hours, the Macau sauna scene might well be a good idea, but it will cost you.
