Did not like: Rigid dining schedule. Food, while plentiful and tasty, was served at a fast pace as the time available for dinner is limited.
Private onsen not worthwhile -- water very hot and space cramped. No after dinner option to socialize. Bar very limited and closes (hard close) at 9 pm.
Upon asking what people do in the evening we were told-- Onsen (bathe)! It is not everyone's preference to take a hot bath after dinner.
