Do I have in-and-out privileges?

In most instances, no. The majority of locations on BestParking, including all those in New York City, do not allow re-entry.

If any specific parking facility does allow for you to come & go during the reserved timeframe, you'll see a "Reentry Allowed" amenity icon listed; this is shown in the details section both pre-purchase and post-purchase.

If you don't see anything on the listing page pertaining to specifically to reentry privileges, it's best to assume that you will not be allowed to come and go throughout the duration of your parking pass.
