I've heard of people doign that.
Do cars get towed from that area nightly?
If that area doesn't allow parking from like 11pm-7am type of thing, they would probably tow all cars during that time...
In which case your car couldnt' of been there all night
Other than that, I've heard of people doing it...
I think it would work for like one day, but after that beware as they may tag your car for towing if its not picked up within 24 hours after that (and from what I've heard those tags are a BI*** to get off lol)
So yeah it'd probably work but wouldnt' suggest trying it for too long
