I agree with you on this, trying to duck muster drill is irresponsible and a sign of immaturity. I do have to admit I prefer the way Princess holds the drill by assembling people in the public lounges, rather that under the lifeboats like RCCI, although it is hard to beat the comic effect of a bride in her gown shuffling along with her oh so attractive orange life jacket on.
The subject generated quite a heated thread on brand X cruise board. The most heat was from ridiculing those who hid in the bath to avoid the drill. On here there was minor heat when someone who later became staff on this board admitted to ducking the drill.
Grow up folks! It is at most 20 minutes out of your precious cruise!
