The Greenland cruises are crazy expensive, I know because we're booked on one next year. In 2019, we were booked on the Sunrise from NYC to Bermuda. Because of a hurricane, we were diverted to Charleston. We received a 100% FCC which was very generous. Not saying that they should get the same for missing Greenland, which was the whole point of the cruise, but $400 OBC per cabin was a little chintzy.
