Sorry, Wendy. Didn't realize you were flying into and out of Fort Lauderdale but cruising out of Miami. Not sure how many people are in your group, but for transportation to Miami, you may want to consider a one way car rental from Fort Lauderdale Airport to Miami Airport, then taking a taxi from Miami airport to the Port of Miami. Fare from the Miami airport to the port is $24 per cab (not per person), flat rate.
Again, not sure how many are in your party, but the car rental option may be the cheapest if there are a lot of people.
