Thank you both. It’s nice to get a little insight on the areas, and interesting to learn about the shopping aspect. My husband and I will definitely keep it in mind for the future. We actually saw a different B2B that does Jeju, Nagasaki, overnight in Kobe, and Tokyo. Although he didn’t voice that he liked it better, and never would never sway us either way, he seemed to perk up a bit more when we showed him that itinerary. While tomorrow is never promised for anybody, I know what the odds are as to who has less time (especially for that long of a plane flight).
Of course the ideal way would be a land trip, but the cruise will give my dad a chance to see a few different places, and the travel between them will be easier for him. Plus, he will have the option of doing things on sea days and at night and not feel obligated to be around my husband and me.
Thanks again.
