To answer you guys questions about the costs. The Chiva bus is around 2, 500 to the spas. The spa is 26, 000 to get in. No time limit, stay as long as you want. There's a cafe inside.
But the strange thing is that the spa doesn't provide anything. No towels, bathing suits, shirts, hats, sandals nada. You have to bring all that stuff with you. They have a room to check your clothes into.
There's 4 large pools to soak in and some small individual tubs also.
