just a comment about revenue:
of course Disney wants -EVERYONE- who passes thru their gate to pay, they're a business not a charity. The non transferable was added to stop the stree vendors from bilking unsuspecting would be park goers from buying bogus tix. (Heck I've been offered $50 for my tix when there wasn't anything left on them.. why? because they knew they could sell them to someone who had no clue) Also, EBAY gets out of hand. By doing the Bioscan they've effectively stopped (or have tried to) people from being unsanctioned resellers of disney matter.
