When we were at Blizzard Beach in April they must have been testing the barcode system. At the end of the day when we turned in our locker key, we had a choice of a mug or $1. This did not include soda. We chose the mug because what good is $1 at WDW? Anyway dh was thirsty so he bought a soda and when he went to the soda machine a kid was standing there waving his barcoded mug back and forth and everyone in the vicinity was filling up their free mug! I had a long talk with my boys explaining why it was wrong, but it sure was tough with so many people taking advantage of it
