I have to laugh, when we cruised the Sun the frist time we thought of her as huge, now we call her small. It is amazing how our ideas change. As for the truely todays mega ships, I would only do one just to see what they are like, but the idea of 4000 or more on one vessel, to me, is not appealing. Just getting on and off would be a hassle. That is why the mega ships can't tender. It would take all day just to get the passengers off.
