If you’ve never been on a cruise before, you might be assuming that anything goes once you’re at sea. However, as any seasoned cruise-goer can tell you, there are a lot of don’ts when it comes to making the most of your trip. Here are a few things to avoid when you go on your next cruise.

Leaving Data On

If you have an unlimited data plan, you might be in for a nasty shock if you forget to turn off your data once you’re at sea. Phones are often doing things in the background, like updating apps, so you could be incurring tons of charges even if you aren’t using your phone to check Facebook. Even if your plan covers you for the locations your cruise is stopping in, the space between can be a grey area. To avoid unpleasant surprises, consider leaving data on as #1 on a list of things not to do on a cruise!

Going on Every Tour

For cruises that stop in fun, cool locations, you might be tempted to go on every single guided tour or excursion that is offered. While some are definitely a good idea and can make sure you skip the line in tourist-heavy locations, they can be expensive and a waste of time if there are other things you want to see or do. Wandering around by yourself in a strange location can be intimidating, but as long as it’s a safe area, going rogue can be the best way to really see the place and get to know it.

Another little-known tip is that, on days when most of the ship is off doing tourist excursions, you’re free to stay on board and enjoy the peace and quiet. Take advantage of the empty gyms, pools, and spas, or just hang out in your room to watch TV and order room service. Feeling pressure to do every single activity can make a cruise much more stressful than it needs to be, so consider what you really want to do and have fun.

Eating All Day

What could be worse than finding yourself two days into a cruise and already being sick of all the eating and drinking? It can be tough to control yourself when you’re surrounded by fun dining options and easy-access drinks and desserts. Especially at those complimentary buffets and meals, it’s tempting to get the most out of your money by overeating and drinking. But your wallet, digestive system, and future self will thank you for exercising moderation as you get into your daily routine on board. And if you do give in and overeat a few times, take advantage of the steps to upper decks or hit the gym so you can make some room for later.

Forgoing Insurance

Travel insurance isn’t something most people think to consider before going on a cruise. But if you’re spending upwards of thousands of dollars on a week-long trip, there’s a lot that can go wrong. Getting sick or injured can land you back at home with a ticket you can’t get a refund for, and having to go to the doctor aboard the ship can be expensive. It’s always a good idea to check your cruise line’s cancellation policies so you can be prepared if something goes wrong. Get travel insurance so you can have real peace of mind as you relax on deck with a blended cocktail.

Getting Burnt

So many people will go on cruises after a winter indoors and forget to bring their sunblock. One day in the pool without remembering sun protection can land you in your cabin for days with a sunburn, and too much exposure can make you seriously sick. Remember to pack and apply sunscreen daily, as well as utilize hats, UV clothes, and umbrellas to limit unnecessary exposure. Taking precautions may not sound like the key to a fun cruise, but being prepared and avoiding things that can be a health hazard or a waste of time and money will ultimately make your trip a lot more enjoyable.
