JerseyItalian is correct. There will be girls all over so don't limit yourself to those places. The owner of Rancho Típico actually took over City Lights for a while and it became the de facto new rhumbas. There are a bunch of bars on the strip and just have fun.
Thanks Swizz416. I will be in the POP area beginning this Sunday. I will stay one night (next Friday night) in Sosua ("So-Sewer"). I also enjoy a little time there. I will post a short update upon my return. As you say, there are always a few good places to hunt.
