(Quick disclaimer: I know this can be a highly politicized topic with strong emotions from some; this is simply a reminder in case you need to plan accordingly.)
In line with ocean environmental efforts Sandals & Beaches has ceased offering plastic straws at all the resorts and instead uses study, cardboard straws. While I have found these more robust and longer lasting than those you have likely had in your home cities, this can be an issue for some people who prefer a forever-rigid straw.
In this instance, I recommend that you simply bring a metal straw found on somewhere like Amazon; these can come in awesome, cool colors, are easy to pack (and often foldable), and allow you to customize your experience! Check out our shopping recommendations here!
