Just my two cents so far. My family embarked in Singapore and we've been on the ship for a week.
So far, I have to say that I don't understand the negative reviews. My previous cruise experiences have been exclusively Disney cruises (Fantasy/Dream/Wonder) so I can most easily compare to those ships.
- The ship is brand new. Everything is literally gleaming.
- The clientele appears to be mostly retirees. It's therefore not obviously designed for kids. With that said, my two daughters (7 and 10) are having a ton of fun. One unexpected side effect of being on a ship without a lot of kids is that there isn't a lot of pressure on the swimming pools. There is a kids swimming pool on the top deck that is almost always empty (or mostly empty).
- Buffet food seems a little worse than Disney cruises - fruit is not quite as fresh or juicy. Still perfectly adequate, though.
- Bakery items are delicious. The International Cafe on Deck 5 serves super-delicious donuts.
- For those craving ice cream, there is free unlimited soft-serve ice cream on the top deck at Swirls Ice Cream Bar from 11:30am to 9pm.
- The pizza, hot dogs, and hamburgers are (IMO) better than Disney. Pizza is served made-to-order in Alfredo's Pizzeria on deck 6 midship and it's delicious. Hot dogs and hamburgers are served made-to-order from Lobster Grill on the top floor next to the pool-- they're super fresh and delicious as well.
- The staterooms have two TVs each. On video-on-demand, there is a reasonable selection of movies to watch-- everything from Zootopia and Trolls to Lalaland and Batman v Superman.
- The staterooms are very nice and (of course) brand new. Unlike the Disney cruises, there is only a single sink/bathroom, but that's not a huge deal.
- Internet is metered by time, not by the megabyte. $199 for 600 minutes for the duration of the cruise.
- General entertainment is not as spectacular as Disney but still super-fun. No mini-Broadway musicals-- juggling acts, singing acts, and the like.
- The staff is (mostly) cheerful and helpful. Not quite as universally over-the-top cheerful as staff on Disney cruises but totally fine.
- The "Destination Expert" presentations about each port are very well done (currently done by a fellow named Hutch)-- he tells you what to expect when getting into each port.
- We haven't tried the youth and teen centers, so I can't comment on those. I can't really comment on the casino or the shops either-- they seem nice enough but we don't spend any time there.
Overall, my kids like the cruise just as much as Disney cruises; my wife and I concur. It's a beautiful new ship with welcoming staff and good food-- not sure what else folks expect!
