Warning: I did this on a prior cruise and the Premier Package was not recognized upon boarding. One of us could not board as the medallion did not work. After they allowed us to board and after we got our WiFi connected, or so we thought, we went to Alfredo's for lunch. We ordered drinks and waited over two overs to be served. By the time we got back to the room charges were hitting our account for the drinks. We went back to the restaurant and they had no explanation. This happened several times throughout the cruise so many wasted hours were spent at Guest Services getting the charges removed. Finally, make sure the bartender is giving you what you paid for. For example, the wine bars will have premier wines but the normal bars may not so you never know for sure what you are getting. Please carefully monitor your onboard account and be sure to resolve all issues before leaving the ship.
