Carnival plc is a very well run corporation. Mr. Arison is a very strong Chairman. I own both Carnival and plc. I also own Berkshire which is run by one of the sharpest persons on earth. Mr. Arison is in the same league. They do not intend to have unfortunate situations occur. Things happen. I will see you on a Princess cruise on Aug 12. Fear not.
If you think Carnival Plc. (LSE: CCL) and Carnival Corp. (NYSE: CCL) are well run corporations, buy the stock. And buy some shares of General Motors (NYSE: GM), too. They are run about the same way.
A well run corporation is not the same thing as a well run ship.
