Lots of tour operators pushing it as the "new" great holiday destination so I am sure there will be fun to be had there,

I found the island of Sao Vicente the most happening spot. In the capital, Mindelo, a disco near the main plaza (forgot its name. No mistake possible) was the main hangout. Lots of girls, though not much quality. Not hardened pros, but mostly semi-pros who like to be seduced (a general trend in the islands). Also many men looking for female tourists.
