Most of the Walt Disney World Resorts offer a refillable mug program for their guests. Refills are available at the beverage dispensers found at the food courts at the Value and Moderate resorts and at specified counter service locations Deluxe/DVC properties.
The variety of drinks depends on the resort – but usually include: coffee, soda, ice tea, hot chocolate, and fruit drinks such as Hi-C, Powerade, and Lemonade.  Milk and 100% fruit juice such as Orange or Apple are NOT available for the mugs.
These mugs contain an RFID chip that is read by the machine in order to determine refill eligibility. The RFID chip will be activated at the time of purchase and programmed to the appropriate number of days purchased.
