I found this:
All staterooms will have a stocked minibar. The items will be replenished twice daily as the items are consumed and charged to the guest's Sail & Sign Account along with a 15% restocking charge. If the guest wishes to have the minibar permanently locked, they must contact the Information Desk. The minibar service will be locked on the night prior to debarkation. Offered on the following ships: Spirit, Pride, Legend, Conquest, Glory, Miracle, Valor and aboard the Triumph and Victory in category 11 and 12 suites.
The minibar will be stocked with premium liquor, wine, beer, soft drinks and a variety of sweet/salty snacks.
