I chose this cruise because I hadn't tried the Carnival brand yet. I have cruised 37 times now, across 7 different brands.
I had been warned about the dark decor, and yes, the majority of the ship has dark decor.
There is a webcam on the midship Lido pool, that streams live into all the cabins - like the ship's webcam at the front. I thought this was VERY weird and unnecessary. It also meant that people avoided this pool, and the rear pool was busier.
