I have had over 10 NCL cruises, all pre pandemic, and never once have we stood near a life boat. Muster drills were always held at the muster station, at least on GEm, dawn, and Getaway. Is going outside something that they have changed or are you just speculating based on what other lines do?
Or as the Chief says have you just been on older ships with large promenade decks and that is why you have been outside?
