Sea and space
I'm not up on current research, but back when I was doing space station designs the studies at the time seemed to indicate that there was no apparent relation between sensitivity to seasickness and space sickness.
While some space habitat designers had a lot of fun designing habitats with no up or down, and people oriented every which way, I insisted on designing modules with distinct "up" and "down" cues, including colors, orientation of furniture, and lighting. I had good reasons.
