when we booked in january they guaranteed the card not charged it. but when we changed the res to match our new travel dates, end of february, the CM said that it was now policy to always charge, BUT since we were on the dining plan, they will be 'holding back' TS credits, 2 per person. so when we check in we will all have 7 ts credits and can choose to pay out of pocket for the HDD or have 2 TS taken off on the spot.this means that for the 7 peopel in our party, people who want to pay out of pocket can or they can pay with TS at hotel check in. So if going on the dining plan i would ask that they hold back 2 ts credits. However they still want a credit card so that if u don't show up they charge the credit card
