Not so sure as to how many are actually made fresh in the park. because last December at around midnight, there was a big truck with the name Abdul on the side, pull up to DLR, where upon arriving several cast members scurried about to assist unloading the goods in the back of the truck, what I saw was box after box after box of candy canes. So, I asked the driver about it, and he said that his cousins make a lot of these candy canes in their kitchen.
selling to Disney, for a rather low price, but then Disney greatly over inflates the cost to the consumer, but will happily pay it because it's Disney.
Enjoy
