This past December, I did a 1 way FLL-MIA and since MIA went to a consolidated rental facility, Hertz doesn't take renters to the cruise port like they used to when they had individual rental facilities. We got a ride with another agency (their driver said OK--saved a bunch on cab fare & gave the driver a very nice tip). Ended up paying next to nothing with a nice coupon.
We did the same return trip from the cruise port and picked up the car. Booked compact or mid, got a Honda Accord. (I liked the car). Car was in stall & return was OK.
I dislike consolidated facilities. Pay alot of extra in fees for mediocre service.
Next time, I will rent from the HLE closer to the cruise port. The prices were much higher than the airport at the time of my rental.
