The included beverage package will be for wine/beer with lunch & dinner only, but you can pay $20/day upgrade to the open bar package (with a small number of exceptions like sake in Red Ginger, Louis 16 cognac, a couple of malt whiskys), but I've always found the upgraded package to be better than the all inclusives I have sailed on. The wine by the glass selection is limited, but covers a broad spectrum & was way better than the paint stripper that Silversea served up at every meal 4 years ago (that cruise put me off South African wine for a long time!). There is nothing to sign when on the package the sommelier/bartender will just ask to swipe your card once in each venue & sometimes they don't even bother.
