As people who have possibly been on multiple cruise and have done the muster drill many times have to remember, there are people on their first cruise ever who have never done a muster drill so they may not know what is expected of them.
This is some of what I posted back in 2023
"I posted this back in March and still believe it to be true.
It was unofficially reported the the main reason Disney went back to the old style drills was because of lack of sufficient participation on the part of the guest. So I guess some may have ruined it for others.
Remember this also gives the crew, especially new crew a chance to also train. These are the people who are going to help save your life in an emergency while people are running around panicking because they do not know where their muster station is.
In an emergency even if people are only half paying attention at the in person muster drill they got some of the information and at least know where to go. If the guest can't remember where to go than thats their fault not the cruise lines. they did their part.
If only one person had to check in at the staging area and no one from the party bothered to watched the in room video because it took up to much time from their cruise this is a problem.
In an emergency especially, if the rest of the party is separate from the person who went to their muster area they might not know where to go.
On our last cruise on the Fantasy in November 2022 from the time the horn blew to start the drill till the time we were released from our muster station it was exactly 20 minutes. And our muster station was on the Starboard side of the ship in the sun.
If there are people who cant stand in the sun for 20 minutes they should find out from the cruise line if there is an alternative place they can meet.
I do not think 20 minutes is a lot to ask from people to help protect their safety in an emergency. this was on a cruise that was 142 hours long so 20 minutes is not a lot to ask..
I posted this in June
One of the things I read was that if a room had four people in it one person would gather all the Key to The World cards and go to the muster station to check in. That meant that potentially three people did not know where the muster station was. Potentially, during an emergency if every one from the room was not together some people did no know where to go.
It may have been apparent to Disney, guest either not knowing what to do or intentionally, possibly not doing what Disney wanted them to due may caused Disney to go back to the old muster drill. This is all of course just speculation as that Disney has never as far as I know put out an official statement.
Second update, our last cruise was December 2, 2023 on the Fantasy and the muster drill was still only 20 minutes."
I also posted this
"I think it comes down to this, this is the way Disney wants the muster drill done. If you want to sail on Disney then for now we will have to do it their way.
I still think the in person muster drill is the best way to make sure everyone has been shown what is expected of them in an emergency.
Of all the times I have sailed Disney (14 times) I have not thought the in person muster drill was an inconvenience.
For my wife and I 20 minutes is not a lot to ask of us to ensure we have been told what to do and where to be in an emergency.
I have also said in the past, maybe Disney has not heard from a significant number of it's guest that they would like to go to a different kind of muster drill other than the in person drill."
And this
"This is some of what I posted earlier,
"It was unofficially reported the the main reason Disney went back to the old style drills was because of lack of sufficient participation on the part of the guest."
Of course this is all speculation because as far as I know Disney has never officially said why they went back to the old muster drill.
So according to the article above, it sounds like Royal and Carnivals guest are doing what is expected of them to comply with the rules to allow them to keep doing the virtual muster drill."
