married couple is going to Lake Toya hot springs over the New Year holidays. What are some recommended lodgings with a view of Mt. Yotei and Lake Toya?

married couple and I are planning to go on a trip to Hokkaido during the New Year holidays. We can stay for about a week, so we are planning to spend a night at Lake Toya Onsen. Please let us know of an inn with a room and an open-air bath with a panoramic view of the snow-capped Mt. Yotei and Lake Toya. I've heard that an open-air bath in the cold and snowy weather is something special!
