They are also reducing passenger load for the 12 day - bumping and offering full refunds and credits toward another cruise or two. Some folks have reported a 200% credit.
They seem to be having some issues getting the new crew up to speed in such short notice. Remember the re-flagging as a US ship has resulted in just about a 100 % turnover in the crew.
Hope things settle down shortly. Many want this bold experiment to work.
