I just went on NCL. The safety video is part of online check in 21 days prior to sailing so at midnight when you just want to check in to get a early PAT. As soon as I was on the ship I was pointed to my muster station but I had no bearings to have any idea how I had gotten there and was still processing what part of the ship and what deck I was on. I could not tell you at all where my muster station was and no way could I have easily made it there from my stateroom.
NCLs was faster but I feel
DCL's is safer.
