The Hotel is incredible. It's one of the best spa experiences I've had. You do have to strip down nude and if that is not something you are comfortable with, do not go for the spa experience. However, you can book a room with a bathtub that is big enough for two. I will say I was dissapointed with the dinner and breakfast at the Hotel and there aren't really any restaurants out that way. If you are only staying one night, I would bring food rather than pay a lot of money for a mediocre dinner. That being said it was one of the best things I did in Hokkaido. If I travel to Japan again, I will definitely go back for at least 2 nights.
