Without a valid Driver's license, a passenger cannot rent a car, and it is a rule in the United States. Operating agencies can check passenger's documents and see the validity of them. If there are on point, then passengers can rent a car.
Renting a car is comfortable there, as there are many operating agencies, such as Rental18, who offer their service at a low price, and sometimes even with discounts, their number is 888-484-3454. There is a West Palm Beach car agency and Bajar Car Agency, which offer economic class models, as well as expensive cars.
