During the purchasing process, select the date you plan to arrive. After making the online payment you will receive a voucher via email with you reservation code.
On the date of your reservation, enter the parking lot as usual, take a ticket at the entrance and park in any empty spot.
Once you have got out of your car, go over to the Hotel's reception with your Parclick receipt of purchase and the ticket you have taken. There our personnel will check your reservation using your booking reference and will give you a ticket which allows you to enter and leave the car park multiple times.
