I used an Olympus D-510, a pocket camera which is now very obsolete, but cost $700 a few years ago, and an Nikon D70. In good lighting the pictures turn out similar, it is in dark or tricky lighting that the Nikon really shines.
Getting laid, my main goal was to tour around the countryside and meet the people, but I will share what I learned…. In the tourist areas there are quite a few police, and the ladies are hesitant to be seen with tourists. Ladies can be charged/fined if found with tourists, and if they get a few fines they may find themselves in jail. Guys setting up tourist with ladies can go directly to jail. Even at the local diso, I made a point of standing alone, expecting to be rushed by hordes of ladies, but nothing. If you are connected, there are still ladies around in the tourist areas looking to meet a nice guy, but you need the time and connections.
In the countryside where I spent most of my time, the ladies would be happy to chat, and would give me their name and address suggesting that we could go register with the police and spend the week together. To offer these ladies money would be an insult. The other issue in the country was that everyone knows each other, so the ladies were worried about gossip. There were people that would hook you up with their cousin, sister-in-law, etc and rent you a room for $5. The girls did not want money for service, but would be happy to be given $20 to help her out with school, baby etc.
In the smaller cities like Holguin, and in Banes there is no problem meeting up with ladies. I spent some time in Banes, which is a dusty little city in the middle of nowhere, no tourists and no police. It took the locals, one of them being a retired Canadian guy that married a young girl and was living with her parents in the town, maybe 5-10 minutes to hook me up with a girl room etc. Unfortunately, the first time when they insisted on setting things up I realized that the sun was setting and I had to drive 40Km back to the resort in the dark, so I left. The girl in the picture at the cottage is another girl that they set me up with to tour around the countryside with. Sadly, the girl, or her mother, got nervous after a couple of days and she did not want to be seen outside with me, police worries. So they set me up with another lady, but she was older, missing some teeth… so I bolted.
Met some guys at the airport that were sold on Santiago as the city to go to meet up with ladies. This city is away from the tourist area, ie few police, and is big enough to offer some selection for the guys and anonymity to the ladies.
