18 sauna is the best although slightly more expensive. They can have upto 80-100 girls to choose. There is a nude girl dance show every 1/2 hr followed by a parade around the pool. So you can take ur time to choose and no pressure. The girls wear different colours based on nationalities, model category or level of services. Ask manager to give you a run down. A lot of girls will offer to come back to your hotel afterwards for overnight stay. Do not take up their VIP card offer its not worth it. Emperor opposite Wynn hotel also has lots of choices, but you can have 50-100 girls line up all at once and it's harder to choose and I've found services not as good. A lot of saunas share the girls.
Do not take taxi driver tips on which Sauna and I think they get commission.
Venetian WL in the lobby are better than Lisboa which has got worse reccently and they will approach you if you are alone and some even follow u to the lift.
