He was getting around 310 pesos to $1 USD.
So, $100 * 310 = 31,000 Cuban Pesos (CUP).
9,000 CUP / 310 = $29 USD (say 30 USD for easy math) - this was a common price quoted for anything less than 1 hour in the sack. I sometimes got 1-2 hours for this price, but if I was with them that long, it was because I really enjoyed their company and generally gave them $40 or a little more for that time.
What I realized when I was there the 3rd time especially, was that the girls really prefer receiving USD, even if you give them an equivalent in CUP. So I decided not to change much USD to CUP, but just use USD for the girls, and even in restaurants and bars where they were offering "street" exchange rates, basically anything approaching 300:1 (my personal cutoff was 275, it was close enough). Many, many places you could order food or drinks, pay in USD, then get a nice chunk of pesos back in exchange for use with tricycle cabs, buying waters, snacks, tips, etc.
Made it easier and I wasn't constantly running around getting change, or getting a mountain of pesos at the beginning and being stuck with them on departure day.
But just go with what is easiest for you.
[QUOTE=Noobie92;2976656]Where are King Santo's currency conversion rates coming from? He says he paid 9000 pesos to the first girl. That's $375 USD according to google. But he also says he gets 31 k pesos for $100. Does anyone know how much he means by 9000 pesos? What are girls going for in Havana?[/QUOTE]
El Toque and Telegram are your best friends in regards to rates.

Right now it's 340 to the dollar. Where I was changing my money, they were consistently giving me 5 pesos above whatever was on El Toque so right about now I'd expect to get 345 in that place. Look into my "Day 1" post which goes into detail about how to get the best rates. It's super easy.
There are conflicting opinions on whether you should be paying in CUP or USD but I can only speak on my experience. I cut my teeth mongering in Santo Domingo where I only pay in Dominican pesos, so I just carried that same M. O. Over to Cuba. I never had an issue.
My reasoning is this: When I change my money to pesos, I know the rate that I got. When I'm at a restaurant, I have no idea what rate they're going to decide to use for USD and on all of the bills I received, the number that they quoted in dollars on the bill was always higher than what I was paying in CUP. Now, was it a big difference? No, maybe a $4-$6 swing each way, but it adds up and I'm not in the business of giving away free money. Like the previous poster said, evaluate your options and do what works best for you.
Best,
KingSanto.
