You can also buy it on the official website, but comparing prices on KKday isn't as cost-effective. You can also earn credit card rewards from the shopping guide, which might make it cheaper. I recommend Taiko no Yu RR; you can soak in all the hot spring waters at once. If you want to relax, you can lie on a lounge chair in the open-air bath (but there are ants). There are also souvenir shops on the first floor where you can buy everything at once (but they don't have the famous carbonated pancakes; you can buy them before you catch the bus). It's easy to spend a whole day there without realizing it.
