We stayed there our last night. We spent most of our trip at the Poly but our flight got cancelled and they didn't have any more rooms at the Poly. There's a snack shop close to Chef Mickey's and if you take your mug there they get get you a drink. They don't actually use your mug but you can get free refills. They did tell us that they will soon get a place to refill it on your own.
I'll say that it was much better at the Poly. There were more drinks available there (no root beer at the Contemp) and you can fill it 24 hours a day. The snack shop closes around midnight.
