Excellent service, food, amenities, and atmosphere. We stayed for 5 nights and each dinner and breakfast was delicious.
The ski lift is walkable from the ryokan, but be prepared for a nice hike uphill. We did it with not that much snow on the ground, so I don't know how difficult it would be with ice or compacted snow.
The hotel has a shuttle to pick you up at the main bus stop. I'd recommend sending your bags ahead of you.
