Question about fast pass, and how it works. Let me explain the situation and see if anyone knows the answer. I will be heading to WDW in june and a member of my party will be attending a local conf. and will not be around during most days, but around for the night. Can i use their ticket to get an extra fastpass tix or does the system not recognizing passes that haven't been swiped in for the day yet? Or does the system assume because you are in the park you used this ticket to get in?
