for dance clubs in the complex, your choices are very limited...Roadway, Hemmingways, and Mangu...unless something else has opened up, that I havent heard about. I have been to all three, even though when i went to Hemmingways it was dead at that time...I hear it does get better than when i saw it...but it is smallish, as is Roadway....on a firday night roadway will be packed....I saw Tono Rosario there one night. Mangus is a little bit bigger...and probably had a more diverse crowd....even if it was obvious there were lots of groups of vacationers there....
you probably have time to check out all three...and you could even check them all out in a single night.....
I dont think you could classify any with an age group...it totally depends on the mix of vacationers.
good luck
