9 Things You Should Never Do on a Cruise
These expert health and safety tips will help guarantee smooth sailing on your next trip.
Ah, cruising is the life. You’re practically waited on hand and foot. With all of the cool activities on board (IMAX, gambling, facials!) you’re never bored; there’s yummy food galore; and the booze is flowing. But before you leave port, here are a few pointers you should know to avoid getting sick or injured at sea.
1. Don’t buy health insurance from the cruise line
When you book your trip you may be offered insurance. But it’s probably best to pass, says industry expert Ross Klein, PhD, who runs the site CruiseJunkie.com. While health insurance is certainly a good idea (a medevac can cost more than $100K), ideally you want your insurer to be independent of the cruise line to avoid a conflict of interest, he explains. Check with your own health insurance company to see what expenses are covered abroad. If you need extra coverage, consider short-term supplemental travel insurance. The Centers for Disease Control and Prevention (CDC) offers guidelines to help you select a good policy.
2. Don’t go without getting your shots
The CDC urges cruisers to make sure they’re up to date on routine vaccines like measles/mumps/rubella, since you’ll be living in close quarters with crew and fellow passengers from countries where these diseases are more common. You should also look up each of the ship's destinations to check for health alerts, and any additional vaccine or medication recommendations.
3. Don’t get too paranoid about the buffet
Self-serve meals might give you the heebie-jeebies, but you can trust that the food served on American cruise ships is safe to eat, says Sarah Krieger, MPH, RDN, a nutritionist who specializes in food safety issues. Dishes are held at the proper temperature and consistently monitored. But if you’re worried, Krieger suggests sticking to food that is steaming hot, and skipping food that's at at room temp, and thus carries a higher risk of pathogens. And needless to say, if something looks bad, steer clear.
4. But don’t go crazy at the buffet either
The biggest buffet risk, says Krieger, is approaching it like a personal eating challenge: “Food is everywhere on a cruise," she says, which makes it all too easy to overindulge and come back with extra bulges you didn’t want. Kreiger’s tip: Try to strike a balance between food that’s nutritious (veggies) and food that feeds your soul (ice cream!). For example, says Krieger, if you have Belgian waffles and bacon for breakfast, choose a Caprese salad for lunch, and a lean burger and glass of wine at dinner.
5. Don’t eat too late at night
It never occurs to you to have a pizza snack after dinner… until you get on a boat. Jimmy Minardi, a personal trainer on Long Island, New York, advises his clients to close the kitchen (so to speak) two hours after the sun goes down. “Late night eating is the kiss of death. There’s a lot of drinking involved on a cruise and the combination of food and booze basically turns you into a sloth,” he says. Besides, food digests better when you’re moving around—not when you’re trying to snooze on a heavy stomach.
6. Don’t get your teeth whitened
Cruise ships often offer teeth whitening sessions—and they are not a good idea, says Clifton M. Carey, PhD, a professor at the School of Dental Medicine at the University of Colorado Anschutz Medical Campus. Sure, you want a sparkling vacay picture-worthy smile. But whitening on the high seas can entail serious risks. For one, it’s unlikely that a professional dentist will perform the procedure. And two, “once a cruise ship is in international waters, they can use incredibly aggressive whitening ingredients on teeth,” says Carey. “This can destroy the protein structure of teeth and can cause a lot of pain.”
7. Don’t drink the water
You’ve heard this before, but if you’re in a developing country, tap water, fountain drinks, freshly squeezed juice, and any beverage with ice in it can make you ill if the water is contaminated. “As a foreign traveler personally, I’ve been told that Americans are like newborn babies—very fragile bodies when it comes to germs,” says Krieger. The water on the ship will be safe to drink, but Krieger recommends that when you’re on land, you opt for the safest possible option: bottled sparkling water.
8. Don’t hire a personal trainer
It’s smart to stay active on holiday, but don’t go, er, overboard. Hiring a personal trainer on a ship is expensive, and fitness classes, from spin to TRX, also cost extra. Save your money, says Minardi. “There are plenty of things that are free that will keep you fit on vacation,” says Minardi. For example, there are stairs everywhere on cruise ships, so take a walk after every meal. And when you get off the boat, explore the port cities on foot.
Plus: When you hire a trainer on a ship, you don’t know his or experience level, Minardi points out. What's more, someone who sees you only once or twice won’t have time to learn about your strengths and weaknesses, and a shoulder strain is not the kind of souvenir you want.
9. Don’t overdo it on the cocktails
If you signed up for a prepaid bar package, it’s temping to drink more than you would if you were paying per beverage. But be careful with the booze: Walking around a cruise ship is tricky enough when you’re sober. There are slippery surfaces, steep steps, and raised thresholds that can trip you up. After three daiquiris, your risk of falling rises, and your judgment becomes … questionable. Climbing the ship’s railing for a better view or a photo opp may suddenly seem like a terrific idea. But climbing the railing is never a good idea. While numbers are hard to come by, some reports suggest that seven or more people fall off cruise ships every year.
