Normal
They definately check rooms. I remember trying to hide with a buddy of mine once. We were extremely drunk. I have a vague memory of the steward coming in our room and holding my arms up over my head as he put our vests on. Somehow I ended up at my muster station, which I had know idea where it was. Needless to say, I find the experience quite fun. We like to hit each other with the things on too, and do like a chest bump.
