You can reserve a Zipcar for as little as one hour or as long as 14 days at a time. Reservations can be made in half-hour increments.
When booking, keep in mind that your Zipcar is available for others to reserve before and after your reservation. Make sure to give yourself enough time so that you don't impact another member's trip if you get caught in traffic.
If the vehicle is not in an existing reservation, you can scan in up to 14 minutes early without incurring any additional charges.
