Can't pay cash at the toll? Credit?If you do take the turnpike in a rental car, be aware that in miami you cannot pay cash and they will photo your tag and bill you. In my past experience, that means the rental car copmany will charge you for a hefty admin fee on top of the charge for the toll fee. So maybe just better to stay off the turnpike if you have a rental car. I just opted to exit right after paying cash before i got to miami and went east to 95.
