I have a car rental from 9pm Friday to 9pm Sunday, currently at $32 per day. It doesn't mention any hourly rate.

There is a strong chance I will be returning the car ~11pm (2 hours late). Pricing out 2 day 2 hour options this late now is not giving any good rates, so I'm thinking of doing a late-fees. But I've never done this before. So what can I reasonably expect in overage charges for late fees here (this is for LAX rental if it matters).
