The second was to verify the safety of its passengers and its crew. Check. The next order of business was to notify the coast guard and Carnival Cruise lines. Check.. The next was to restore as much power as possible. Check. The next order of business was to arrange to be towed to the closest port. Check.

Don't see anywhere that Carnival hasn't in place plans to address any and every situation that could possibly come up. The fact that they have had to work and move to different plans is indicative that they have worked out, in advance, a clear policy to follow. I'll always cruise Carnival, or one of its divisions, or any other cruise line. They are prepared, even if it might not appear to be.
