Welll ....
I live in Cabarete and hang out with the local crowd! It has a pumping nightlife every day of the week, but of course Fri and Sat are the best nights because people come from Santiago and the Capital and its a great party. My suggestion would be start out at Lax and then when that closes at one head to Bambu, Onnos, or Crazy West! Those are the three "clubs/discos" on the beach. You can actually dance there, Jose O Shea's is more of a touristy "just get drunk" place!
Have fun!
SSSSSiiiiiiiddddd
