Anyone else have issues with their number of free drinks getting calculated incorrectly? Last month on the Vision, several nights, I was getting "charged" for one or more free drinks in the MDR in error. So when I go to the Schooner or another bar later, I think I still have free drinks available, but they tell me I've used them all. Not sure how it happened, but it was very frustrating, and I found myself at guest services too many times getting the charges removed. How can this be avoided going forward? I do not get the beverage package, just my five free daily.
