This boat has been sold out for some time on the Paul Gauguin

All the airline ways to get to Bali are falling through and who knows whether they get back online for all Pax by mid May. Same for return out of Fiji. Can the boat go to all its neat stops including Guadalcanal or will it have to pass by/substitute others.

These aren’t cheap cruises (like 1000$ a day for two and it hasn’t cancelled yet.
If the cruise line cancels, It would seem the refund is pretty simple.
But if the boat is ready to sail, but no one can get to it, who takes the hit, the Pax or Bn?
