Can we ski one area (e.g. Suginohara) in the morning, and another area in the afternoon (e.g. Akakura)?
You could in-theory do this, however we recommend skiing in one area for the whole day. For example, if you would like to ski Suginohara we recommend going there in the morning, and skiing there all day until the afternoon. This is in order to maximise ski time, make best use of lift tickets and there is plenty of terrain to explore in each resort to keep you entertained for the day.
