I think you should consider moving it. I think Hurricane season is July through October. The other months are cool. Hurricane/Tropical Storms season is very unpredictable, sometimes you get one and other times you get 5. Last year, I knew someone who was on the cruise during the earthquake and the hurricane. They missed ports and had to turn back. Keep in mind that the "rainy" season for your port of calls, so if you are doing your wedding off of the ship, it won't get rain out. I guess it wont be so bad, if you were doing your wedding the day you board, but I think you are gambling with "mother nature" during this time. Also check out the months, that the cruise line adds a surcharge. Best wishes on your decision.
