 And it's affecting all the cruise lines out there in the ocean. Cruise lines are altering some of their cruise courses in the Caribbean as Hurricane Beryl storms through the region. Carnival Cruise Line said yesterday it was changing the original trajectories of two of their active cruises, Carnival Horizon and Carnival Liberty. Carnival Horizon originally scheduled to make port at Grand Cayman in the Cayman Islands today, canceled that visit. It scheduled a trip to Cozumel, Mexico on July 4th, also replaced with a visit to Nassau on the Bahamas on July 5th.
