People misbehaving is hardly unique to Carnival, so it is something that can easily be predicted. The ship had a security team. If supplies are limited, then Carnival should know enough to ration the supplies. There are many reasons issues on the Splendor did not degrade to the level that they did on the Triumph. Sure, maybe on the average the average moral fiber of the Splendor passengers was higher than that of the Triumph passengers, but also Carnival handled thing on the Splendor much better than Carnival did on the Triumph.
