Was there a few weeks ago. I thought th breakfast was very good. I tried to stick to Japanese items like crab soup, rice topped with furikake, smoked fish. Decent selection of bread. They have Hokkaido Apple jam too.
The onsen can get very crowded between 4-6. Mostly Japanese on weekends. And more westerners during the week.
You get a drink coupon as gold as well.
The ski valet is nice but I don’t understand why they need a ticket instead of just using room number. Seems unnecessary and a hassle. I also wish they have vents for boots overnight.
