Those ‘Around the World’ cruises didnt sell out in one day...I got EMails about them...They were presold at special prices about 6 weeks before they went on sale...
Plus the ships are less than half full...
Those around the world cruises will not bail out the cruise lines which need to fill their ships on shorter 7 day cruises- especially filled with Americans leaving from America.
There is a lot of rah-rah and cheerleading talk about cruise ship bookings, but when, and if they go, and at what capacity is not usually mentioned because it does not help the narrative of "book now before we sell out". -Tom
