I'm on the same cruise. I have not received anything from NCL, my TA has not received anything from NCL. I know some people on the roll call have. Our friends in Canada did receive the same letter from their TA. It is very strange not everyone has the same info. When I called NCL they could not confirm or deny any changes
I posted the question to NCL FB group. Lots of people talked about how the channel is being dredge wider. NCL has been canceling stops at Taino Bay for many months. They are docking at Amber Cove IF they have room. I just wish NCL would be honest about it. Changing our itinerary and using the carbon footprint is laughable.
