Why whales in Alaska have been so happy

With the legal hurdles out of the way, the major cruise ship lines have just started returning to Southeast Alaska for a shortened 2021 schedule. The first Royal Caribbean liner, the 2,580-passenger Serenade of the Sea, arrived in July. Holland America, Celebrity, Princess, Norwegian and Carnival are all scheduled for the weeks ahead – totalling tens of thousands of arriving tourists for the month of August.
