Mazatlan has some very interesting cultural tours that take you to villages in the foothills of the Sierra Madre. The Golden Zone has the best shopping (variety and prices) of the three ports. There are also beautiful resorts right on the ocean that will let you use their facilities. Stone Island has great cantinas right on the water with very reasonable shrimp and drinks.
Still a little confused. Would I be able to use their pool for free??? Do you have any idea how much an average all inclusive day might cost?
