Here's why this place is awful:
It's not on even on the airport grounds. You have to wait for a shuttle bus to get to the office and the shuttle only runs every 45 minutes or so.
In the event that you have to fly out super early, there is no after hours drop box for the keys, and you won't be able to get your rental car into the lot in the first place, because the driveway will be blocked by that shuttle bus.
When you DO finagle your car out of the street and into the driveway (blocking the shuttle bus because you don't have another choice), you're basically forced to leave the leave the car keys in the mail slot because THERE IS NO AFTER HOURS DROP OFF and the office doesn't open in tune with early morning flights.
Then, because the office isn't open and the shuttle isn't running to get you to the actual airport property, you have to call a cab or an uber or something to get yourself to the actual terminal. The driver will have an awful time finding you because there are ZERO streetlights anywhere near the Thrifty office and you will have to pay for a car to take you to the airport because you couldn't use your RENTAL CAR to take your damn self to the airport.
THEN! Thrifty will ACCUSE YOU OF STEALING THE FUCKING CAR because you couldn't check it back in properly BECAUSE THEY WEREN'T OPEN AND BECAUSE THEY HAVE NO AFTER HOUR DROP BOX. They had to move the car I rented in order to move their fucking shuttle bus, but they still accused me of stealing the car THEY HAD TO MOVE.
In short, Thrifty may be a decent rental place, but this location can catch a million fires.
