I must admit that I'm a little disheartened about Princess Cruises taking a major media hit in the wake of the COVID-19 crisis. Since 2002, DH and I have sailed exclusively on Princess - 21 cruises to date. We like the understated elegance of Princess ships and the relaxed, quiet ambiance. Princess ships don't have ice rinks, water slides, go-kart tracks, rock-climbing walls, etc. that one finds on other lines. While there are dedicated children's/teens' centers, we rarely see more than a handful of children or teens on our cruises that are usually when school is in session.
Princess tends to attract "older" guests, so I'm thinking that this might be the reason that Princess ships are prone to COVID-19 outbreaks. There have been comments that refer to Princess vessels as "floating nursing homes" due to the high number of older passengers, many using walkers, wheelchairs, and scooters.
