I believe there is a 16 drink limit per day on any drinks package and the difference between easy, easy plus and premium is the cost of drinks themselves. Easy would drinks that are less than $10, so bottom shelf alcohols (generic vodka, rum, etc as well as beer and wine). Not many options in that lowest tier. Easy Plus package would be alcohol up to $10 so Jose Quervo 1800 tequila, Ketel One vodka, and semi-higher end wine and beer. Premium package covers the premium booze (Patron or Don Julio tequila, almost all gins and highest end beer and wine). We were fine with the easy plus. IIRC Most of the drinks of the day were $10. If you're a gin and tonic fan, all of those mixed drinks were over $10. Enjoy your cruise.
