All premium alcoholic beverages are included with the exception of the wine list, which I have only heard of people actually utilizing at dinner, but who knows. The in-room bottles are not premium, as you assumed, but they aren't total shwill either. The best of the in-room booze is probably the Appleton Special rum, which is the distillery's lowest quality blend. The house wines are ok, at best, but they definitely do the trick. As for rum outside of your room, at a minimum, ask for V/X at the bars. The overall selection can vary from bar to bar around the resort, but there is plenty of premium liquor at every bar.
