Why take Risk? run for free while you can afford a little fee? imagine you leave your car today in the Parking, once you fly out of the country in two days time they introduce new rules immediately that long term parking Fees applicable from the date of parking,then suppose you overstay prior to the allowed period which all int'l airport has,mmh your car will be towed away and you'll be slapped with a heavy Parking fine when you're back.... Be Careful..Free things are SOMETIMES Expensive..
