Isn't Zumba led by the entertainment staff, and also, not in the gym? To me this just sounds like a different company taking over, gym classes have a fee, as usual, but now you can also take classes in your room, on demand (on the tv).....I guess for those in the suites, not inside rooms.....lol. If they are smart, they will also keep the free morning stretch class.....gets people into the gym and, maybe, they can upsell them.
