I recently came back from a quick trip to Panama and I thought I would give an updated report. I went down for work, so I wasn't able to see any daytime action.
I stayed at the Marriot and there is a cigar bar across the street called "Habanos" with girls in it. I also visited the casino at the Venetto hotel nearby. The number of girls in both places was really low, but I'm not sure if that was because I was too early (around 9:00pm) or not.
Internet-wise, I came across this website:
http://www.sexy-panama.com with some girls. I attempted to hook up with Andrea, but she was out of the city at the time. She sounded nice on the phone, so I will probably try to contact her the next time that I'm in town.
