My son arrives in Japan a week after I do and right at the start of Golden Week. I want to reserve a seat for him so we can travel together the first couple of days using our Rail passes.
Please advise if
(1) I can reserve a seat for him when I make my own reservation before he arrives (ie 2 seats on one pass at the same time)
(2) I can reserve a seat for me at one office and then use my pass to reserve a second seat at another office?
I know this second option is not strictly playing by the rules but I expect the start of Golden Week to be very difficult for reservations when he arrives
Appreciate advice from the forum.
