Included dinner was great and it was a 4 course meal. Breakfast was also great with unlimited bread. At 4pm onwards, you can use the hot bath.
Dinning room and living room have heaters so you won't worry about being cold. Room also has heater that you can set as you like. Fyi, it's the norm in Hakuba to charge extra for that heating, it was 500 yen a day.
