Can anyone tell me the current price of a cup of coffee from the Kona coffee bar at the Poly? I'm trying to decide if the mug would be worth the $12 since I only drink one cup of coffee ea. a.m., and we'll be there for 7 days. I don't drink soda, and wouldn't use it for much else. Can it even be used at the Kona coffee bar, or only at Capt. Cooks?
