Don't you hate it when deck parties end early because a pirate ship appears on the horizon? 2,000 passengers aboard the Sea Princess were told "close and lock their balcony doors, then lock their entrance door to their cabin and take shelter in the corridors." A passenger told CNN the ship banned late night activities because of pirates. Apparently, pirates prey upon passenger ships all the time. But this time, the Sea Princess told CNN precautionary measures were taking place. It was a just a drill, folks!
