Can I get a car after 11:30 pm at the san diego airport?

Most likely... But avoid this company they are terrible

We won't rent from SD location again.

Yes you can there open 24. As long as you already have a pickup order. So with that said drop off is 24hours for sure. Another thing just find a different car rent all the cheap ones are not . The sale prices says 29 a day after they up sell and add tax and charges and what ever they want your looking at 129 a day ya that much of a difference. ..plus gas on the road. So run from this place....

Yes

I don't think so, but I would call them & try to make special arrangements. They ask for your flight info when you reserve the car so it's likely you could arrange something.
