need directions in miami

Im planning another rail/cruise trip in March

Amtrak Silver Star Philadelphia-Ft.Lauderdale and staying in a cheap-o motel for a few days

Then Tri-Rail Ft.Lauderdale to Miami Int’l Airport to circumvent Amtrak Miami station.

Whats the best routing via taxi or public transit to get from the airport to the port.

This trip is costing my wife and I a mint so looking to save a few bucks to get to the port/

Be sure to check with the cruise lines. They probably know the answer to your question. Also, they may even provide free transportation themselves.
