Miracle! Got a Sunrise Twin room just before departure! How to get this Super Premier Room!

This time, we traveled from Takamatsu to Tokyo on the Sunrise Seto, but we could only reserve two single rooms for two adults by one month prior booking. After further trials to secure a twin room, we miraculously managed to secure a Sunrise Twin room just before boarding. I hope you will try your best to get a twin room, too, as I show in the video how I managed to secure this premier room, of which there were only four rooms available per train.
