Wow, that seems rougher than when I was on the Freedom back in October of 2010, right around the same time. Only that time, we were sailing from Grand Cayman to Cozumel. If I'm counting right, I think that was day 5 of a 7 day cruise, on the Western Caribbean itinerary.
We actually skipped Grand Cayman due to bad weather. We were in the harbor, seeing if we could get in, and I went up to the Windjammer for breakfast. I saw it was dark, windy, and rainy, and thought "Oh, this can't be good." Sure enough, it was deemed too dangerous for the tenders to run, and Grand Cayman closed the port, so we had a day at sea.
