You can bring your Refillable Resort Mug (Rapid Fill) back to a Disney hotel on a future trip, but it will not work for free refills. Each mug contains an RFID chip that is programmed to expire at the end of your original stay (up to 14 days). In 2026, if you want to reuse your old physical mug to save on plastic waste, you must take it to a Quick Service location and pay for a new activation. The cost for this reactivation is typically the same as buying a brand-new mug (currently around $21.99). Most guests choose to just buy a new mug to get the latest seasonal design, as there is no financial discount for bringing your own back. Note that these mugs only provide unlimited refills of soda, coffee, and tea at Disney Resort hotels; they do not work at the refill stations inside the four main theme parks or at the water parks unless you purchase a separate "Water Park" refillable mug on the day of your visit.
