What happens if you leave your car in the lot overnight?

I left my car there overnight in 2017. It was fine when i picked it up the next day at 11.

I didn't think you could leave your car at all overnight, but maybe they do give you 24 hours and then they would tow it

I don't know the answer to your question, but I believe you have 24 hrs to get your car, (giving you time to recover from ur hangover :0) or risk the chance to be towed away. Parking lot attendants monitor every day and tag cars if left pass 24 hrs.
