I'm guessing you are flying down to Miami, then sail from there?
If so, I recommend you book a hotel for a day before and go early. The weather can turn nasty and a lot of flight delays and cancelations.
Seems every cruise in the winter involves a manitoba snowstorm.
Depending on our flight time out,we may need to book a room near the airport. And they fly us out to miami a day early,put us up in a posh hotel.
