No, nothing is really free. I look at the "Free at Sea" and you were paying 20% on top of what it would have cost you if you had purchased the package separately, i.e. the “free” version of the NCL drink package offer does not include the cost of those gratuities. You are responsible for paying the automatic 20% gratuity that’s assessed against all beverage packages even if you’re selecting it as one of your promotional perks. This entire amount is due up front before you board the cruise. It’s rolled into the total price of your cruise when you book your reservation. Same thing for the specialty dining.
