Ski in/ski out is great, buffet food is average, but the smell in lobby during dinner time is not so good, the smell of grilled foods is everywhere, make it feel kind of cheap. make sure you did reservation of dinner 1 week before otherwise you will have no choice but having buffet everyday with exactly same dishes.
However the snow condition this year/month (2019/12) is pretty good, for a warmer winter this year we got very good powder snow to play with.
The hot spring is also good, but kind lack of Japanese feeling due to full of foreign visitors (most of them are Chinese/Taiwanese), it will be better if the manager of hot spring make sure all the visitors do know the rule of Japanese hot spring manners.
