Our cruise was Sept 18th special eastern, and all was not too too bad until mid week when we had such terrible waves they had to shut down all the pools and practically shut down the whole deck for two days. THen on Friday we were enjoying ourselves when we got an emergency announcement that we had to dock that night at PC, and they were to put us up in the Swan or Dolphin, due to Hurricane Jeanne changing direction. They treated us, according to our party of 11, as well as they could with such a sudden development. People on that cruise were also mailed a 50% voucher for another sailing (which is another can of worms). But, we would do it again in September, and probably will. The weather was amazing, and the prices were worth it.
I think that you have to realize that anytime in the hurricane season it is a possibility, and September a little more so, so do not be too fixated on your ports of call, because they may change.......
