I believe the CP was around $270 for the two days and the RR was $190. This is the backend of the week of my vacation (Sun-Wed is in HNL) so it's all going to come down to how much is spent in Hawaii those days.
Baggage situation is good news!
Is there a tourist card/transportation card for Hiroshima? I think from what I'm reading it's going to be more cost effective to just buy the tickets as I go there. Getting to the Peace Memorial, then somewhere for food, then onto Miyajima.
