I don't know maybe depends on how old you are. I usually do not even go. The cabin steward will come by, if they open the door i tell them i am sick and they leave. I am really sick of going to those things.
I read the evacuation route on the back of the door, follow it and check it out. I mean, eventually if you ever pay attention to anything on a ship you will probably do the evacuation several times during the course of the cruise. also, i make sure we have life jackets.
The reason i say this is because........once at the beach here in Florida my wife and i were swimming in the ocean. Beofre i knew it we couldnt touch. Calmly i asked my wife to swim with me a little more parallel to the shore....what you are supposed to do in a rip current....then we make our way to shore. Moral of the story......you read, hear or learn how do to do things in life but yet never practice them. When the time comes, in an emergency some not all people ....will know what to do.... some., many probably won't. it will be people like me with common sense and acting cool calm and collected that will save a life and many others.
Well thats how i feel. i have been to a couple but not all drills.
