We have never had one, and note that as well as getting them with QSP and DxDDP you can buy them separately. With a split DVC stay you can chose to have two different dining plans during your stay at Disney. As such if you only have the plan with the mug for one part of the stay (with DDP the rest of the time) does the entitlement to refills end, and if so when? If you buy one separately how long do they last? Also are they valid at all Disney resorts or only the resort at which you stay/buy it? How will the CM's know these details? Oh for the simpler days before finding out about the three Disney Dining plans.
