Sixt was easy to use. Bus from Fort Lauderdale airport to rental company, them return to rental company and they shuttle you to the cruise terminal. Prices were reasonable. Even the day we did it with long lines at the cruise terminal and lots of people returning cars, they were very efficient in processing everyone.
I rent in the fort Lauderdale Sixt terminal and return in the Miami parking Six terminal. Good option, and next Uber to ship terminal its really near.
You need to check wich companies have units in both the CruiseShip and in Ft Lauderdale.
