What a disappointment.
I had been looking forward to this cruise for over 10 months and I cannot tell you how many times I visited the MSC USA web site to view all of the amenities of their Yacht Club. It's mostly all lies.
First, you are not shown your cabin by your white gloved butler but by someone who has no stake in the game and pretty much opens the door to your suite for you and then leaves. It took us five minutes to figure out the lighting and power scheme on our own. This is service? Turns out our butler was on break for the first two hours that we were on board.
