Dressing too casually

You’re on holidays at an all-inclusive resort in Hawaii, so it’s swimsuits and flip-flops 24/7, right? While that is true for some areas of the resort, many all-inclusive resorts have upscale dining and shows that require, at the very least, trousers or a sundress and real shoes. You will be turned away if you don’t meet that dress code.
Do this instead: read up on the dress code before you start packing, and make sure to bring at least one outfit that goes beyond beachwear on your packing list. A pair of khakis or trousers and a collared shirt will likely suffice for men, while women should bring a dress (beyond the all-cotton beach cover-up) or nice pants and a blouse. Some resorts have formal nights where suits and formal dresses are required. And don’t forget to pack a pair of dress shoes!
Ignoring safety guidelines

Some guests think weather advisories, public-health mandates (like masks), staying out of roped-off areas, only swimming in designated spots, wearing life jackets and other safety rules are for everyone else but not them. But our safety guidelines aren’t there to mess up your fun – they are to keep you safe so you can have more fun. Ignoring these guidelines can put you in danger and ruin your holiday.
Do this instead: follow the rules, and avoid endangering yourself or others. This is true even if you ‘already know how’ to do an activity (like snorkelling or skiing). Guests ignoring the rules have been caught in dangerous riptides, attacked by wildlife, taken jaw-dropping falls or been stranded on land that suddenly turns into an island when the tide comes in.
Getting dehydrated

Too many tropical holidays have been ruined by heat stroke! You have delicious beverages (both alcoholic and regular treats) at your fingertips, so it’s understandable that you might forget to drink enough water – something that can be compounded by being outdoors more than usual, forgetting sun protection like hats or umbrellas, and loading up on salty snacks. But getting dehydrated can make you feel tired and irritable at best, or gravely ill at worst. This is especially important if you are travelling to a climate that is significantly hotter or drier than you’re used to.
Do this instead: balance out each alcoholic or sugary drink with a glass of water. Take a reusable water bottle and a sun hat with you on excursions, and be on the lookout for signs of dehydration like exhaustion, being overly sweaty or unable to sweat, becoming very red in the face or very pale, disorientation, muscle cramps and weakness.
