I am looking at summer 2024 cruise options and noticed that depending on the itinerary some deposits are nonrefundable. I have cruised Princess for over 20 years and deposits have always been refundable. Is this a new thing since I cruised last year? For example, I am comparing summer 2024 cruises in Alaska, Norway, and the Med and the Med deposit says nonrefundable. But for Norway and Alaska the deposits are refundable. It doesn't matter if I select Standard or Plus.
