I have heard a couple times about a mythical creature known as the Shopping Pass.
Basically, the premise is that you can ask for this at a ticket window (guest services?), and be granted a short window (1-2 hours) to enter a park, purchase things at the in-park stores, and return to the ticket window.
I understand that there is a cost for this that is fully refundable, upon return to a ticket window (guest services?) within the designated time and with proof that you did, indeed, shop at the in-park stores during the window.
Does anyone know anything more? Is this creature truly a Figment of my Imagination, or does it actually exist?
