Are you sure? When I called to ask a few questions before agreeing to add the free dining package stay to our room only stay, I was told that the mug's RFID chip would only work on the soda stations for the length of our dining plan stay. (we are staying 4 nights under the dining plan, and 4 additional nights in the same resort under a room only reservation). I know that the reservations CM's don't always know what they're talking about when it comes to finer details like that, and it wasn't a dealbreaker for me, but has anyone actually successfully done this recently?
