While valet service may be handy we want to make sure that you and the Zipcar stay safe. Zipcards are required to unlock and lock the vehicle and you should never give your Zipcard to another person for your own safety. If any damages were to happen during the valet service you would also be responsible for the full cost. It's easiest if you just take the time to park on your own.
The only time you can use a valet is if the car's home location has a garage attendant. For more information on that please click here.
