Prices Gold's Gym
In fact, they charge 300 pesos per day for use of Gold's Gym, or 2,500 per month.
We go three times per week, there's hardly ever anyone there. It is a fabulous facility but it is hard to see how they can keep it going at that price; the daily air-con bill probably costs more than they take in memberships.
The demographic of Cabarete/Sosua would not ordinarily support a 'normal' Gold's gym running, especially with the competition around, but this one is in an unusual place and subsidized.
