Car Rental at Krabi Airport

Cons: When I arrived at the Krabi airport to drop off the rental car, there were no signs pointing us to where we should go, so we ended up driving around the airport for about half an hour looking for a Hertz sign of some sort, and eventually I just parked the car and ran inside the airport terminal and found a tiny Hertz desk, where the woman asked "Where did you I leave the car?", so clearly that isn't much direction to it.
