My first thought is a money grab by the various cruise lines then file for bankruptcy leaving many people in dry dock.
Some people think it is a continuation of their bait and switch tactics the Lines have used for the last year.
Something I have described as a form of PONZI scheme.
Economically the Cruise Lines are really up against it now and some drastic action has to be taken soon.
How many more BILLIONS can they borrow now with no way of paying it back, except to use borrowed money to meet their obligations. A business like the AIRLINES don't have to worry because the Governments will bail them out - as they have gotten bailed out in the past.
The Cruise lines are on their own.
Something has to give shortly. -Tom
