Do zipcars have to be returned to the same location?
Pick up and return these cars and vans to their same dedicated bay. During your reservation you are able to park in other areas, but if you're stopping over in a space that requires a fee, you're responsible for paying it.
Can you cancel Zipcar membership anytime?
If you have a Family Plan, the memberships of all drivers on your account will be cancelled as well, but they can book cars until the end of your billing cycle. Any trips scheduled after your plan expires will be cancelled.
