hello - i am planning the following trip for 2 (me and my son):
Dec 25 - 26: Tokyo
Dec 27: day trip to Hakone
Dec 28: travel to Shibu Onsen via Nagano
Dec 29-31: Kyoto
Dec 31: Kyoto to Osaka
Jan 1: Mt Koya day trip
Jan 2: Osaka and surrounding area
Jan 3: Osaka to Tokyo
Jan 4-5: Tokyo
Jan 5: flight home from Narita
question: does it make sense to get the 14 day pass for this 12 day itinerary, or rather just get a 7 day pass from Dec 28 - Jan 3? Also, i would like to get the green pass but want to be sure i will be able to make a reservation when i arrive on Dec 25 for the long travel days (Tokyo to Nagano Dec 28; Nagano to Kyoto Dec 29; Osaka to Mt Koya Jan. 1; and Osaka to Tokyo Jan3). Do you think on such short notice over a holiday period it will be difficult to book the green pass reservations on those dates? is it worth it to get the green pass if there is a chance i wont be able to reserve the green pass seats on those days? I am trying to understand how far in advanced these seats get booked. Any guidance you can provide on this would be so helpful. Thank you!!!
