Hertz is located a bit far, but there's a shuttle bus which helps. I came from Terminal 5, the queue was short in the morning, and I got the car quickly. The service was alright, but they recommended too many things. You need to say No to everything, especially when they emphasize that fuel prices are cheaper than the market. If you ask whether you can get a refund for any leftover fuel, they say no. I almost got fooled. It's hard to return the car with an empty tank precisely. Also, after getting the car, carefully check its condition. I found a few scratches that weren't noted in the inspection report, so you need to inform them yourself.
