Does the Sixth Division General Hospital charge for in-patient vehicles?
If hospitals charge parking fees, then they all have a standard time period, such as: free for half an hour, how much for more than half an hour, how much for more than a few hours, and then no charge for more than a few hours, and so on. Every hospital is similar, but there is no case where there is no charge for in-patient vehicles. Or you can ask the inpatient department to see if there is any reduction or exemption of parking fees.
