The only itinerary change you may have to worry about is CocoCay. If it is thunderstorms then it is too risky for the tenders to go back and forth, so you may end up having a day at sea instead. I was on the Majesty during the week of October 1, and it was torrential rain for the first hour or so after we arrived in Nassau then was gone. We were fortunate that we had great weather after that throughout the cruise.
