Royal Caribbean cruise ship in 2021
My cruise is going out of Seattle to Alaska (skipping Canada due to the new, temporary law that allows not having to stop in a foreign port) and the requirement out of Seattle is that everyone 16 and above MUST be vaccinated, so the rules on the ship may be different... but going out of Florida (where a new state law prohibits requiring a vaccine) there are some special rules once on the ship... with, interestingly enough, different rules for the cruises out of the Bahamas where the CDC does not control things, the Bahamas goverment makes the rules
This is going to be my last ever cruise, since there is no other place I want to go, so I am going to enjoy myself while I go 'walkabout' in Sitka and Ketchikan and on a conducted trip in Juneau http://www.royalcaribbean.com/shoreExcursions/product/detail/view.do?ProductCode=JU33
