You will be okay in February. I went in October and sailed eastern caribbean during Hurricane Otto. Our itinerary was changed. The ship did move quite a bit. I didnt get sick because I took Dramamine. However, it makes you very lethargic and drowsy so I did not enjoy myself as I would have had the ship not rocked. But, like I said, you will be fine in February. My next cruise is in April. I'm not sure I would chance an October cruise again.
