You would have to drink more than six "well" drinks per day in order to make this package worth it.
There have been days when I have consumed that many drinks in one day but those days are long gone.
On a Sea Day my wife may consume a total of four or five drinks and I might have one or two. On a port day we'd be lucky to consume three between the two of us.
The final answer is: No. It isn't worth it for us. I can see where it would be a value for some folks but I do believe the sticker shock of the pricing will keep most cruisers and "party hardy" types from purchasing this package and live with the sticker shock at the end of the cruise.
