Sorry, I misunderstood your original question. As far as trying to use it again, I'm sure it's coded as used at the ticket scanners. I had a free pass that I got at the 5K last year. I mistakenly picked it up instead of my season pass. I didn't realize this until the following day when I used it again to enter the park and was told that ticket had already been used. So, I went to Customer Service to get a duplicate of my season pass to get in.
