If you are planning to stay in Port Canaveral the night before, I assume that means you have a car you will be parking as well. Have you been looking at the "snooze and cruise" packages that include your stay as well as your parking for the length of the cruise. I have been looking into doing this and we only live about an hour from the Port. Some of the hotels include breakfast and other extras. The only thing I warn with that is to pay attention to the time the shuttle for the port leaves with each hotel. If you are like me, and want a nice, early Port Arrival Time, there are very few that offer anything before 12 noon. But...they do exist.
