Each cruise ship does muster drills for each cruise. One thing I was glad to see on our recent Holland America cruises was that they seem to be taken more seriously since the Costa Cruise disaster. There are still passengers who think these things are a joke and either try to purposely miss them or just waste time talking and joking around during them. Holland America did take a roll call and did make announcements for people to quiet down and listen. I was also glad to see this. For those of you who think you do not need the drills and want to just goof off through them or try to hide from them what you are actually doing is causing them to take longer then they need to be. If everyone showed up right away and just kept quiet and listened the drills would only take about 10 to 15 minutes instead of 25 to 30 minutes. Believe me the drills are important so please be considerate of the other passengers that are onboard the cruise and cooperate so everyone can go on with having a good time.
