that would be great......the only problem is that cms would still have to play "MUG POLICE". we all know cm don't want to disturb anyone's stay, no matter how wrong they are!
Was thinking more in line of a bar code sticker. Just have the machine stop dispensing after a year. It would stop people from using the mug year after year and Disney increases revenue. During that year people can use the mug as much as they want.
