Well that's tasteless. Usually it's, "please respect our privacy while we grieve", not go on a speaking tour circuit.
I have a legit question since I have only been on yachts and not a cruise ship.
There is a safety drill at the start right? Like on a plane?
And some places that are more dangerous than others (crew areas, operations) do have extra signage, right? But the whole ship is considered to be a place where you are cautious about your surroundings. Like if you have a balcony door open and you open the other door, WHOOSH!!!! Crazy air whirlwind! So dont stand in doorways or leave your hands in the frames. The crew does go over these dangers and other things , right?
I am sure the cruise company has policies that are already going to protect it from these kinds of threats.
