Past posts on this forum regarding overnight bags typically recommend duffel bag for the overnight portion of the essence of Japan trip rather than standard carry-on suitcase. Tauck no longer provides duffel bags for this trip and now specifically recommends a rollaboard carry-on suitcase. Tauck guidelines allow for one suitcase per traveler (ie, tauck will handle/transfer one suitcase), which suggests that travelers must be responsible for their carry-on rollaboard suitcase during the trip.
For portions of the trip that use transportation via motor coach, will Tauck allow carry-on bags to go in the luggage compartment of the bus (overhead bins on motor coaches typically do not accommodate standard carry-on bags)?
For train travel, will standard size (22”) carry-on bags fit in the overhead bins? I am not concerned about lifting a bag into an overhead bin or having to carry a carry-on bag up/down stairs, only wonder whether a regular carry-on bag will fit in the overhead bin.
