I, too, used to be concerned about hurricanes in the fall and never cruised then. We are cruising September 10, this year and I am not worried. As Kuki said, the ships move faster than any hurricane and the captain will not put the ship or passengers in any danger. I would recommend that you make arrangements to arrive in the port city a day early. Sometimes flights are disrupted if there is a storm in the area.

take Kuki and MaryLou's advise. Late season hurricanes are rare, but they do occur, you need to be a bit flexible in your planning. I would definately plan on flying into Ft. Lauderdale a day early, If a hurricane is brewing, your ship will be either diverted to another port or she will put out to sea, you will hear stories about people throwing hissy fits because they missed a specific port because of the weather, what did they want the Captain to do? steer the ship into the hurricane? if it will totally, positively ruin your cruise if you miss a specific port, then cruising might not be for you, you always run the chance that your ports could be changed during your cruise for any number of reasons, not just weather.
