Why does someone need to be jealous, only because they don't enjoy the same things as you do? "The nicer things" well that's in the eye of the beholder.
We normaly sail on Royal, but as a Swede the American "in your face-service" took us a long time to get used to. I still can't say that I enjoy it. Last year we "had to" book MSC since Royal wouldn't let my family sail (due to age restrictions). Started to read a lot about MSC before we sailed and a lot of passangers that normaly sail on Royal said that they hated the lack of service.
We sailed two times on MSC last year for a total of 18nts. Even if I prefer Royal compared to MSC, I think that the "we are here if you need us-service" are a lot more appeling and one of the best things about MSC.
My point is that what someone call "the nicer things" isn't the same for everyone.
