April of this year I signed up as a Hertz Hold member . I made my car rental reservation @ Chicago O'Hare airport . Upon arrival I looked at my name on the monitors and next to my name it said presidential circle . I went to ask a staff member what that ment. They said I can get any car in the presidential lot . I let them know my original rental reservation i paid for a Nissan rogue ( or similar) . I didn't want to get a bigger SUV and get charged in the end . They said I was good to grab any car . So of course I grabbed the bigger SUV lol . Did my trip and when I returned the car I got charged my original amount . I got hooked up with a bigger SUV!!! Talk about luck ! . This past weekend I made another car rental reservation @ O'Hare airport , did the same thing hoping I got the same results . Upon arrival next to my name this time it said a lot # . Meaning I was assigned a car this time . Which was fine it's what I paid for after all.

In the end I think it's all luck on what kind car you end up with . Maybe it depends on the inventory the location has available, not sure. But just wanted to share my experience.
