Sauna 18 at golden dragon hotel is the best in terms of selection of girls and quality. You have about 80 to 100 girls parading around the pool every 30 min following a nude dance act. They wear different colour tags and ask manager to explain the difference.
You can also take your time to choose rather than having to choose from a parade. Girls often asked to go back to hotel with you afterwards and I had a great time with a few of them. Beware taxi drivers will often persuade you to go to other saunas for their kick back. Lisboa hotel foyer is just for experience but services and quality worse. Venetian hotel and surrounds also many girls for pick up. Sauna girls better service usually and they get tested for STDs regularly.
