Deceitful and Pathetic,
Last minute plan changes required me to return the car at 2:00 AM Saturday to catch a 5:00 AM flight and began calling their office Friday evening as soon as I knew of the change of flight. I made 7 attempts from 5:45 PM until nearly midnight and kept getting a "...leave a message" recording then "This mail box is full..."
I had only one option. I drove the car to the exact location from which I picked it up, a small building with parking for about 12 cars. I was surprised to find they had no Drop Box for after hour car key returns, so I hid the key behind a sign on the building. As soon as I landed I called and explained the situation. Instead of a thank you I was told I would have to pay an additional $250 "Abandonment fee". ABANDONMENT FEE???!! Where would they rather I had left it? Their Rental agreement (Nifty, aka Ace, btw) states: Item #4. "...Renter shall return Vehicle to Daily Rental Company..." That's exactly what I did.

RS 32:473.1 Abandoned vehicle - Louisiana State Legislature defines abandoned vehicles as:
… decrepit cars or car wrecks or cars that have become useless in other ways, which are abandoned and illegally dumped in the environment.
How can ACE possibly say I abandoned the vehicle when I returned it to the exact location from which I rented it, cleaner than when I got it and with a full tank of gas?
One of the several documents they flashed before me and had me sign was a document called “Addendum to Rental Agreement”. It covered 10 topics. one called drop off before/ after hours does state, “… prior arrangements must be made at the time of rental if the vehicle is to be returned before or after hours.” That was impossible under these circumstances. Initially I planned to return the car during normal working hours but the need to change to an earlier flight forced me to return the car at 2:00 AM.
This is nothing more than thinly veiled THIEVERY…. Read other reviews, DON’T GET SCAMMED BY THESE CON ARTESTS.
