I just got off Ocean Princess 10 days ago. She does not rock or roll any more or less than any other ship of her size and class.
We were skirting around with Hurricane Michelle (never near it but got some swells etc). Sometimes I wondered if I was on the same ship as other people as each morning you would hear people complain about the bumps the night before while others (like me)
felt that given the seas we encountered it was a nice ride.
I don't think you will experience a bad ride where you are staying.
Enjoy your trip.
