Overall the cruise was a wonderful and positive experience. Maybe a bit too expensive, but it was my first cruise since 2000.
Cabin: I had an inside cabin. My in-laws (both my wife's parents and wife's aunt and uncle) had a balcony cabin across the hall. The bathrooms were great. Great water pressure, hot water, toilets worked well. All that stuff about them being low slung asian toilets isn't really that true. I'm fairly tall, and I thought they were fine.
The balcony cabins were so "roomy" that 5 people could comfortably sit around and play cards. Our inside cab fit 2 twin beds and a pack n play. We thought the setup worked well, and it seemed very typical of what you get on a ship.
9689 on the end. It was great without any defects or issues. Plenty of room for the beds plus a crib. There was a little sitting chair and it was very close to the big theater and the kid's spaces. It was Noisy during shows in the stardust theater, but no other complaints.
