Omicron is making it very difficult for any cruise line to guarantee itineraries.
Let's be honest. If you think you are an experienced cruiser and you are not aware of the current constantly changing environment, then you just might not be an experienced cruiser.

Norwegian used much more Corporate Speak, but that is the bottom line. The necessary letter is below. It seems there are many guests on every cruise line surprised when the itinerary on their cruise changed at the last minute after local authorities denied entry to their ship out of fear.
