There is no discussion area for CANCUN for I am posting it here. Maybe the moderator will start a need section.
Cancun has changed over the years. There used to be a red light district called Playa 21 south of the city, but that is completely gone, although you might see some old reviews that still talk about it.
When I was there the cab driver suggested 'Pleasure Principle', but when he told me the going price was $300 USD, I asked for another option. There apparently are two other options. 'Elen Cantro' and 'La Caldera Del Marquez' the driver said he was taking me to closer one. I didn't see the name, but I assume they are similar. These clubs/brothels are located down town, pretty far from the tourist area. It is about a 10 minute taxi ride (150 pecsos) an located in a mainly in a residential area, although I felt safe at all times.
Entrance fee was $20 USD. I only saw locals, no tourist but me, although the girls spoke pretty good english. The girls were pretty, but not sitting with the locals. It was a little early and maybe the locals were biding their time. The club was loud with a large stage in the center. When I 1st came in there was a girl dancing, but she sat down before I could even get seated and no dancing occurred while I was there.
The girl I talked to was an independent from Cabo who travels around tourist cities. Her price was 1000 pescos ($80) but the on-site room cost was 1200 pescos ($100). She realized that this was an expensive room cost and suggested we meet at my hotel.
I didn't really have much time at this point. So I settled for a couple of table dances and a few beers.
Table dances were about $5 - $10 and beers were about $5 and lady drinks about $10.
There is also apparently street walkers readily available, but expect them to not speak English and probably not very clean
