No you did a great job at explaining. I totally get it now, I'm just amazed that it was even a possibility to do that in the first place. Huh, I never would have guessed. Was this so widely used that it could effect ride times?Apparently, unlike the old legacy FP system (paper), FP+ wasn't validating that the ticket medium you used to get FP+ selections at the kiosks in the park (initial 3 selections) was the same ticket medium you used to enter the park. So a guest could enter with a linked MB and use a "ghost" MB or unused/expired ticket at a park kiosk and get another set of FP+. The park kiosks apparently only read the RFID and didn't link back to admission. From what I was able to glean, this really became popular when some rides were tired at parks.
Others can probably explain it better than I did. Your can go to other Disney forums and see lots of outraged discussion on the crackdown.
