Yes, I have. One time is enough. I think I can also experience in the hot spring zone in Thailand. There are four hot spring pools, each with different temperatures. The highest is about forty degrees. The pool is not big, on the contrary, there are more tourists. The key is poor facilities. Water has a lot of green plankton. It will float on you. The bottom suction edges of the hot spring pool are very slippery. All of them live in a silk of green, which will slip if they are not careful. The way beside the hot spring pool is not easy to walk. The ground is wet and rotten. There is no place for bags. Put it beside you and watch the bag while you soak in the hot spring. Next to the hot spring is the sidewalk, which is completely silent. Personally, I don't feel at all enjoyable. There is neither sun nor shade at noon. The equipment is worse when you run. It's all rotten equipment. The place is fine. It's not imaginary beauty and perfection. Get off at your destination and go on foot. It takes less than ten minutes to walk. There is no clean place to change clothes after rushing. One trip is enough. If you really want to soak in hot springs, don't go. Water is not clean and the environment is not quiet.
