Nothing
Although I was able to make a reservation online, the place was not open when I went to pick up the car. After waiting an hour for the place to open, I went to a different Hertz only to find out that it was a holiday and only certain locations were open. I was very frustrated by the fact that I was allowed to make an online reservation despite Hertz knowing they would be closed that day. No one ever tried to contact me and give me the heads up. Very frustrating experience, would not recommend
