I have a question about the refillable mugs you purchase at the resorts. We will be staying this week at AS Movies and then in Oct. at AS Sports and again in Dec. at AS Music. If I purchase a mug at AS Movies will it be reusable at the other resorts? If anyone has an answer, please let me know. It gets expensive to have a mug from every resort. I know they used to be interchangeable but not sure if the rules have changed!!!
