As previously noted, the rules for now do not reqiure you wear lifevests to the drills.
This will hopefully be change back to reqiuring them soon with the Concordia investigation and rule change recommendations.
That said, everyone in the Maritime industry(with the possible exception of some of the office staff of the cruise lines), we all say the same thing..........put it on, learn how to secure it properly to the drill.
A ship in a emergency condition, with her rolling and pitching, lighting reduced or off..possible fire, vessel sinking......passageways crowded with people.....people frightened.....paincing, that is NOT the time to look for it, figiure out how to put it on and get to your station.
Before anyone brings it up........if you have it on properly there with be no straps hanging down to trip over!
And NO there are NOT enough vests at the boats for everyone! ( That is a new rule being considerred)
