We're not really drinkers, can take or leave it. Our rule of thumb is if it's part of the cruise deal we book we enjoy the ease of it. Otherwise we just pay as we go if we want a drink. We don't drink enough to make the beverage package worth it.
We bring refillable bottles and a travel mug for coffee. We're happy with water, iced tea and coffee. My husband brings water enhancer drops for flavor.
Hope this helps. YMMV.
