My husband and I were scheduled to go on a Norwegian cruise the end of October 2022. He recently passed away. We have insurance through cruise line and I have decided to go on cruise since there will be other family members going also. My question is - the prices have dropped on this cruise and if I were to book today as a single it would be a significant savings to what we booked as a double. So I am wondering if the cruise line will refund the difference or even do a FCC or whether this would be something I could claim on my travel insurance.
