From what I can tell - If you haven't seen a video from that commenter before YouTube's algo gives you an immediate bias to that commenter's circle of similar viewers. It's only for a few days though and if you don't follow up/like/subscribe to those channels then the algo reverts back to your current baseline (de-weights that circle).
I follow a fair number of disney/park vlogs (thanks to that stupid algo!) and I've not seen any counters to this current hype train. The only "positive" info is coming from those vlogs that are just relaying the disney blog info and some of whom are probably going to get some of those early trips on board the cruiser.
Some food for thought - assuming they stay fully booked - $6000/night X 100 rooms x 7 days a week = ~4.2 million a week. Now that's a base line because, presumably, not all the rooms will be fully booked at all times and also some people will be paying more as they'll have more people in a room, paying for the suites, etc;. But that means you've got a yearly gross income average of 220 million. Which seems like a lot but in addition to housekeeping you have to have an active live entertainment budget which is fixed into that cost as well as dining (unlike, say, the Polynesian' Luau which is an added expense). There's no scale to move there (aside from rising ticket prices or cutting perks) as they can't just add another tower to increase room count. (Compare that to a Disney Magic Ship which has similar rates but which has 875 rooms)
Given THAT - I'm beginning to understand Disney's mindset here vs what we were all dreaming of.
