Was in Punta Cana last march. Wonderful time, but take whatever you want to smoke. There is really no place to buy CC's that you can guarantee aren't fakes, and a lot of the NC's were shady too especially the fuentes. All the CC's I saw at the resort and in local shops were fakes. Only place I saw that had legit ones was a small cigar factory/store we took a tour at.
