This is all just quick and top of head from last week's cruise.
Best things:
--4 major entertainment shows (OceanAria, Chicago, Blue Planet, Ice Show) were outstanding in quality and execution (and I have been going to NYC/Broadway shows regularly for 20 yrs). You will be pleasantly surprised that a cruise line can produce this much variety, quality, and originality. All shows are produced in-house except ice show which is outsourced. 1 major show (Headliner) merely very good. Dreamworks kids shows very good, probably 'outstanding' if you are a kid that has seen the movies these shows are based on.
No electrical outlet ever found in Grand Suite bathroom. If there is one there, you need to help cruiser locate it or place one next to each sink where it is most useful. If there is an outlet reachable from beds, where is it? Never located it. Without extension cords we would have been really inconvenienced on our trip.
