WHAT??? Your comparing Disney to Burger King or McDonalds?? Seriously??? Wooowwww!!!! Last I checked unlimited refills at BK an McDonalds were only good when you are sitting down to eat in the restaurant. You can't leave and go back the next day,or even the same day for that matter and expect to be able to get a free refill. I would love to see you try it and then tell the worker at the restaurant," I already bought the cup and it says unlimited refills." when they confront you. The cop they call to come and arrest you for theft would probably get a good laugh as well!!
Speaking of purchasing volume. BK and McDonalds must get as good a deal on soda as well. So that comparison is invalid. Plain and simple the resort mugs have always been unlimited refills for length of stay. If you bring them back on your next trip and get soda. YOU ARE STEALING!!!!!!! There is no way you or anyone can justify refilling their mug from a previous visit,knowing it is one time use mug and then try to use the excuse 'Well it's Disney, they can afford it."
Micromanaging? No quite the opposite. I am glad that some "beancounter" came up with this idea. He/She is saving the company money,and that way the losses are not having to be passed onto to the guests or myself by raising prices to recover the losses.
