We have sailed several times in December out of Florida. A couple of times, we had to wear long pants for embarkation, but we wore shorts the rest of the cruise. December weather is usually great for cruising.
Thank you for your help. We will be leaving out of New Orleans.
I think we will take some jeans and a light jacket for late nights on the deck. When we was on our cruise in June we would go get a slice of pizza and sit out on the deck almost every night.
