I haven’t solved the mystery of shipboard public address systems. The calls to lifeboat drills are blasted out everywhere – not to be missed – can’t be hidden from. Other times and other announcements – can’t hear a peep. Sometimes you hear a mutter and have to run to the balcony or cabin door and stand outside to hear the disembarkation notices or wildlife/nature narration. Interesting to see the dishabille of some of the neighbors…
