Hello,
We are family of 5 (me, wife, son (11), daughter (8) and son (4).
We will be traveling to these places in 10 days.
Haneda airport ==>Tokyo==> Hakone==> Kyoto==>Osaka==>Tokyo==>Narita airport.
Can you please offer any advice as to what ticket to purchase? We would prefer fastest trains and to select seats in advance if possible.
Thank you!
