Cabin R40 (Riviera) on the Carnival Fascination was great. There were no stairs nearby and nothing but other cabins above us. No noise from below. Also, R40 is not adjoined to the cabin next to it, so that was a benefit.
My first experience with a “sideways” interior. I liked the room layout, but there was this horrible “whump whump whump whump” sound in the cabin. It was worse over the bed at the wall with the “window” than it was at the other bed, so I made DD sleep in the noisy bed.
I didn’t even bother to complain as the ship was full.
Next time, I’ll stick to a “regular” interior on Riviera or Main.
