The poolside bar does have a refill station located to the right. They also have a few options for food as well but most of their items count as Table Service points.
We just came back from a 10 day stay at Kidani Village and I have to say that the only negative is the lack of a food court there. Next time we will upgrade from a studio to a one bedroom so we can have the kitchen and laundry. We soon became tired of the food at The Mara, as well as the trek to get there. We did enjoy our one dinner at Sanaa.
No coffee at the pool...And the coffee at the the gift shop was not good at all during our stay...You may want to think about making coffee in the room.
