WATCH OUT! Default pickup / drop off time adjustable in the reservation preferences: These times are just what we’ll use when creating the reservation to begin with. When setting up your pickup and drop off hours per location, we recommend you to make sure your default times are included within this timeframe. Let's say, you allow pickups between 9AM and 12AM. In this case you'll want for example to have 10AM as default pickup time but not 13AM.
