I have just noticed that it has been added to the DDP for 2013. We have never bothered with one because we drive and we bring snacks and drinks. Can you only refill it at your resort? I'm just not aware of the rules with it.
Yup. Only at your resort. And it only includes the drinks at the pop-fountain area. As well as coffee, tea, and hot chocolate. Milk and Juice are not available.
