Indoors and outdoors are very fun. In addition to slides and artificial waves, there are swimming pools and hot springs. Be sure to bring bath towels, shampoo and other toiletries in advance. It is best to buy beach socks. The indoor temperature is higher than the outdoor. The swimming ring is best to go before you get angry. The water and food inside are not too expensive. If you want to swim in the pool, it is best to bring a swimming cap, otherwise you will not be allowed in.
