Norwegian pulled the plug on May last week.
Also 2nd time cancelled, pushed it to June 2021
Boston had about 80 trips scheduled on different cruise lines in 2021 .
If Canada stays closed only a handfull will go, and those will be Bermuda trips, weather permitting.
You can see that is a problem for the cruise lines to figure out. If you can't get to and back from Bermuda because of bad weather, you cant really go further south to the Bahamas; and legally you need a foreign port in the trip. -Tom
