I would think the only way to figure out if a drink package is worthwhile is to know the prices of drinks beforehand so you can factor it up. For example, I am a teetotaler so if I looked at a drink plan it would be either the Specialty Hot Drinks or Premium Non Alcoholic. The issue is without knowing what Hot Chocolates, Tea Fortes, non alcoholic Cocktails et al cost it is hard to make an informed decision.
