It all boils down to how much you drink? If you have a couple alcoholic drinks a day don’t get the beverage package. But like others say coffees, waters and drinks add up.
If you like to drink and consume a lot of cocktails then you may be better off with the AI.
My DW doesn’t doesn’t drink that much a few cocktails where I consume a few more.
But who’s counting. We have AI on our April cruise and will just roll with that. DW wants a martini or something not on the Classic list then we pay the difference.
There’s plenty to chose from.
