I try to avoid extra sugary drinks. Other than tequila, either on the rocks or neat, and Martinis, I like the Beverly Hills Iced Tea, it’s similar to a Long Island Iced Tea but has sparkling wine instead of coke & it has simple syrup. I just tell them no simple syrup.
Its really hard to find not so sugary drinks, even their Margaritas use the sugary sweet & sour mix so I stay away from those.
The good thing is if you don’t like a drink, you can just order something else.
The less ingredients a drink has, the better it will be as far as sugar goes.
Have a great cruise and enjoy your drink package!
