I don't know about the South Beach tour but we had a late flight (6:40pm) out of Ft Lauderdale and we ended up renting a car real cheap at the airport and spent the day at the beach. The Ft Lauderdale Beach was less than a 10 minute drive from the airport. The person at the rental car agency said they always like to keep some extra cars just for the cruisers with later flights. We cruised the Imagination on March 3. Great ship!
