We just got back and the refillable mugs are now resort wide. When we were sold ours, we got a real run down of the rules by the CM. Disney is dealing with the resort hopping mug abuse by allowing these mugs at any resort. They are not, however, good at the parks. For some reason, people think they are and we saw a bunch of them trying to get free refills at the parks. Leave it at the resort - it won't do you any good. They are really stressing the good for the length of your stay aspect, too, and the mugs do have the year 2007 on them, so I assume the style will change every year. I think the resort specific mugs are gone forever.
