Ok, so here is my opinion....Do I prefer the virtual muster just watch a video scan my key card and done...absolutely!!!! Do I like the traditional muster drill? Absolutely not! Will it ever ruin my 1st day onboard? Absolutely NOT.
Why one cruise line does it one way and the others do it another will always be up for debate. I love cruising NCL, and this process will not discourage me to cruise with them, but if it bothers someone else that much we all have the opportunity to cruise other lines.
