I kinda agree with this. You could just purchase the "mug" and have that implicated on your Keys to the World Card. They have a little machine that you swipe your card and you dispense your drink. Expires at Midnight on the night you check out. We always purchase new mugs when we go because we use them at home so for us it's like part of our souveniers. I've seen people using mugs that are YEARS old. I would never say anything, but it's those little things that jack up the prices.
Looks like their would be options "the proposed system allows for either unlimited or controlled refills with any cup/vessel using token-based authentication."
