Flights are not included in this proposal and will become available to book about 11 months prior to return date. Budget $1000-$2000 per person for main cabin.
Please note that with the time zone changes, you will arrive in Japan one day later than you depart the US. Your return flight will probably arrive the "same day" even though the journey will take ~16.5 hours.
Pre- and post-cruise hotels are also not included but can be quoted. We highly recommend you arrive in Tokyo at least one day prior to the cruise's departure to allow for flight delays and cancellations.
