La isla...I've heard nothing about it, including radio and the papers....Last time I passed Punta Cana was still empty. They have closed in the past though, they might reopen.
Problem with Salsathèque is that the guys are way too agressive (if you follow
)
6/49 is hard-core, they don't like non-salsa dancers. It's corner ste-cat and peel in a basement. Another good Salsa location is Le Cactus.
Sundays best bet is Salsafolies....best in the summer on the pier in le vieux-port though.
Good luck,
Hit me up if you have any more questions!
