Unfortunately, at The Parking Spot, you will not be able to make overlapping reservations on your Spot Club account. If you need to make a second reservation, you will need to logout of your Spot Club account, make the second reservation and checkout as a guest using a different email.
If you are looking to make multiple reservations with your points, we will need to have your points transferred to other Spot Club accounts so they can redeem them for a reservation.
