I parked a car there for seven days and had no problems.
Since it is well known the cars parked there are left overnight for many days in a row I would be very surprised if they were left unguarded at night.
That being said - all car parking lots limit their liability - so I would very careful about not leaving anything valuable in the car - and if it is a commonly stolen model - just make sure your insurance is up to date.
It's up to you.
