Where do I leave rental when dropping after hours and is there a drop box

Haven't used a dropbox. Sorry.

I just park in any open space and drop my keys in the drop box by the door. They will check it in and email you a receipt the following morning.

Anywhere near the front. Some locations has a drop box key in the door or sitting in front of the door

Yes, there is a Dropbox. You can leave the car at the store.

Yes there is. Just put the key in the box and leave the car.
