I commented years ago on one of the original threads on this topic.. but, as someone who cruises on multiple lines, it makes me laugh at how folks on here will so blindly defend the Mouse and fail to acknowledge that other cruise lines can, AND DO, handle muster way better than Disney does. I love the "Disney cares more about safety than other cruise lines" argument?

Really? Give me a break... all major lines are fairly well vested in ensuring the safety of their guests. "More kids" -- false narrative.
Royal Caribbean's Oasis and Icon class ships carry considerably more children week-to-week than does any of Disney's ships.
As an aside, our last
Disney cruise was on the Fantasy a couple years ago... our muster station was outside on the promenade and the drill commenced during the middle of a thunderstorm (not uncommon in Florida during the late afternoon). It was utter chaos. Nobody could hear anything. There was thunder & lightning. Kids were crying.. some were scared. Parents were stressed out. I'm sorry, but nobody will be able to convince me that was a "safer" approach (quite the contrary, in fact) than what's being offered now on almost every other major cruise line with regard to handling the muster drill.
Disney will do what they want to do. That's fine. And, many folks on here will stanchly and blindly defend this antiquated process as well. That's fine too. To each their own...
