We stayed at CBR on our last trip and even though we had the Parking slip in the front windshield one of the parking CM's still made me take my AP out of it's holder and show it to him. At the time I didn't realize that you got free parking when you are staying onsite. I just thought it was weird that he actually checked the AP since it was in this years holder which is different from the 2000 holder. I guess next time I will just flash the resort parking slip and/or my room key.
