Over the year-end and New Year holidays, I spent two nights and three days split between Karuizawa and Niigata, one night at a hotel in Karuizawa, and one night at my brother's place, which I was visiting for the first time. I came back home on January 1st to avoid the U-turn travel rush. Last time I went on a two-night, three-day trip, I counted the title's #DAY XX as covering two days, so I'll do the same this time.
