All-inclusive drinks are watered down garbage. Hotels design them to keep you buzzed but not drunk so you spend on other stuff.

The "premium" upgrade? Still bottom shelf, just not the absolute worst.

Buy a bottle at duty free or OXXO stores. They're everywhere. Bring drinks to beach or pre-game in your room.

For actual good drinks, hit local bars downtown or nicer Hotel Zone spots not part of your resort. Costs more but you'll taste actual alcohol.
