Do any of the parking lots in PHL (on- or off-airport) offer any sort of a grace period for exceeding 24 hours?
As an example, I will be arriving at 5PM one day, but leaving at 7PM the next day. Many parking lots at EWR give you a 3-hour 'grace period,' where I would not be charged for another day until 8PM that day (5PM + 3 hour 'grace period'). Do any PHL parking lots offer a similar policy?
