Having never been on a brand new ship, we did the 5 nights to Tasmania to experience it. Walking on board was full of "wow" moments, the kids water park, the North Star, Seaplex complex with the dodgem cars, we definitely want to bring our grandson on board one day to enjoy all the fun things. I'm sad to say the North Star was closed the day we were booked as winds were so high but will try it next time.
A tip I picked up from other cruisers is install the Royal Caribbean App on your device before going on board - it was very useful to book everything and see what was going on, although there are ipads everywhere on board to check with if you don't have the App, BTW it is free.
The decor is so modern and different, Cafe 270 is the most versatile we've ever experienced, so much going on and then to see the technology in action is inspiring. 270 venue hosts a show called Pixels at night, however we had trouble seeing it all as not many seats offer full viewing so our tip would be go early and get as close to the front as possible.The theatre show Live, Love,Legs was one of the best ever, although on this short cruise not much else was on offer in the main theatre.
Cabin was new, lovely decor, decent sized balcony for 2 to relax on, stewards looked after us very well, what more could you ask for?
