You can order from your wine package at Palo or Remy, you can also exchange a bottle so to speak, so if you want one of the recommended ones at Palo or Remy, you will just pay the price difference in the bottles.
As a note, from the math I have done, the wine package is not a significant discount unless you order the most expensive bottles every night. Unless they started putting better wines or more expensive ones on the list, it was no discount the last time I sailed which was in October 2014. Of course, better is subjective to your taste, but I was not a fan of many of the whites on the list, so found myself consistently longing to just be ordering a bottle of white off the regular menu. :/
