I haven't made myself clear. I have no issue with the suites, butler, and those amenities nor do I have any problem with the guests. I get you want/get a better room. My issue is with the amount of public space given to YC on MSC. The YC pool restaurant and buffet take up 30% of the public areas for 10% of the guests. I wouldn't even mind this if the remaining 70% of the public areas were not overflowing with people. Put simply: the ship is too crowded for the amount of square footage attributed to the number of guests. When I am wall-to-wall with people on a sun bathing deck and I can see an empty sun bathing deck and I'm not allowed to use it, that is just adding insult to injury.
My favorite ship is the Norwegian Gem, a jewel class. It does have a "haven" which is identical to the YC. I couldn't care less about it because: 1) its not in my face, and most importantly: 2) the rest of the ship easily accommodates us other passengers. I've never had to wait for dinner, wait for lounge chair, been shut out of a show, couldn't get a drink, ... on the NG. On the bigger ships that is not true.
The worst was the Norwegian breakaway. I measured the actual square footage of the public area. The ship has 40% more public area than the Norwegian Gem, but 70% more people. That's already too crowded. What made it unacceptable was that 20% of that public area was for 1st class and I was denied access. Basically I was on the same ship at the Gem but with twice the number of people. You had to literally wait for groups ahead of you for elevators. It felt like a subway. MSC was the same thing: 33% of the elevators are for 10% of the passengers, while the other 66% is stuck waiting on elevators while 1/3 of the elevators are sitting idle.
