It really is tough planning for a Fall cruise to that part of the country. It can be warm and sunny, or cool and rainy. We've encountered both types at that time of year and everything in between. You pretty much won't know what to actually pack in your suitcase until a few days before your cruise and get the chance to check the weather forecast. Just plan for any scenario and put what you'll need in the luggage when you're ready to go.
