There are times when parking your own vehicle at an event can prove problematic. Inclement weather can turn the walk from the car to the venue into torture test, ruining expensive clothing and shoes. There may not be enough available parking near the hotel, shopping mall, etc meaning a long walk through city streets at night. A driver may be able to drop his or her passengers off at the entrance to a glamorous event, but he or she will still have to make a less glamorous trek from the parking lot after wards. Because of these concerns, many upscale Hotels, Malls offer valet parking.
An advantage of valet parking is that it is possible to park more cars into same space, in what is generally known as “Stack Parking”. The reason is that the valets holds all the keys and is able to park cars two or more deep, because he can move cars out of the way to free blocked-in car.
