I'm planning on taking the JR train from Hakodate to Sapporo on April 29 this year, which is (I think) the first day of Golden Week. I'll be with my parents.
Anyone have any idea how crowded it'll be? Should I buy tickets ahead of time, and how much ahead of time? Do I need reserved seats? It's a three- to four- hour ride, and I don't want my elderly parents to have to stand that long. We are thinking of leaving around 3:00pm. We are also open to taking the bus if the trains are going to be full, although it'll take longer.
