Are you asking if there's an opt out?
There will be, apparently, in the legal sense only. Somewhere here I compared it to having to agree to a 33-page contract at a kiosk in order to rent a car. You have a choice? Sure, you can spent a week reading it and consulting with your lawyer or you can walk or you can just do what 99.9999% of people do and go right on through to the 'I accept' button and drive away.
WDW's ticketing operation and $7.83 an hour CMs simply aren't/won't be trained in how to explain to guests what RFID tech is how they can 'opt in' ('cause that's a positive ... you're in ... you're getting something special ... you don't really want to be out do you? Like a loser?)
But don't ask me, ask
Nick.Franklin@Disney.com. Or one of my pals in Celebration, I'm sure Blondie would love to help you if Tommy is under his desk after this week and Crazy Gary is out staking his dragon over at IOA.
