the voucher redemption process is fast, there is a 20k deposit that will be returned at the exit, the entrance ticket price changes, the through ticket to the pool is cheaper than buying it separately, there are many food and souvenir stalls, there are also mat and mini zoo rentals, there are also massage services for both men and women, the toilets for flushing and bathing are not very clean and the rinse water is still sulfur water so it still stings the eyes and the toilets outside are paid 5k for a shower, it's a bit expensive because we bought the entrance ticket and thought it was already rinsed
