Getting this room
- Book it by name. Choose "New wing room with open-air onsen bath" (新館露天風呂付客室). Only some rooms have the bath.
- Ask what the website doesn't say. It doesn't mention free-flowing spring, the view, the beds.
- Check the confirmation. It should name the room with the bath. If it doesn't, contact the property.
