We stayed for eight nights in Shiga Kogen for a ski holiday in early February. The position is ideal - in Ichinose across the road from the ticket office and ski lifts and a minute walk to the bus stop. Downstairs is a cool bar with nice food, drinks, video screen and the occasional band.
The hotel itself is a little dated and tired, like many in Shiga. The staff are very helpful and kind, but the room was only thoroughly cleaned every second day, and just tidied the other days. The onsen was piping hot, and great to relax sore muscles after a day on the snow. Breakfast was good, with a mixture of western and Japanese dishes. Dinner was also quite elaborate, but too many cold dishes after a long days skiing. I would try to book room and breakfast only, and eat at the bar if you can.
