Cruise ships are known for having some strict, and often strange, rules for their guests. Because these massive ships set sail for life on the high seas, certain precautions must be taken to assure that everyone comes back to the land in one piece.

Rules keep order, and no one is going to have a stellar vacation with complete chaos ensuing.

These fifteen rules that the famous Royal Caribbean Cruise company created are pretty intense, and there seems to be zero wiggle room where they are involved. You either follow the rules, or you can enjoy a vacation somewhere else. What they say goes.

While sailing the ocean blue, the travelers are definitely not calling the shots.

15 Keep Scissors Short

You can bring scissors with you when you board a Royal Caribbean Cruise ship, but they have to be a specific length. Per the Royal Caribbean website, guests can bring scissors that are less than four inches in length. You better make sure you measure your trimmers prior to boarding if you plan on taking them along.

14 Leave the CBD products At Home

CBD products are all the rage these days. They come in snacks, oils, lotions, and so much more. Some people love them so much that the thought of traveling without them is unheard of. Guests who hope to set sail on a Royal Caribbean ship will have to choose to leave their CBD products behind. They are not allowed on board.

13 Baby Monitors Are Also Not Allowed On Board

One strange thing that Royal Caribbean cruise lines do not allow parents to bring along with them on their vacation is a baby monitor. To be fair, you should not be leaving your kiddo in your room and heading out to experience all that the cruise ship has to offer.

12 Adult Beverages, Except 2 Bottles Of Vino, Are A No

Some cruise lines won't allow any liquids to accompany passengers with them on their trip, but Royal Caribbean is a little bit different in this respect. They do allow their guests to bring two bottles of wine or champagne with them when they board. If they purchase more vino at a port, then the ship will gladly store it for them.

11 Need To Cancel? You Might Be Out Of Money

Sometimes unfortunate circumstances arise, and travelers need to cancel their cruise plans. Those who have booked with Royal Caribbean might be out of luck, though, because their cancellation policies are known for being pretty strict. For a booking six nights or longer, trips have to be canceled seventy-five days in advance.

10 Swimwear Must Stay On The Pool Deck

Bathing suits are popular on cruise ships. Just think about all of that sun on the seas and the tanning decks that surround the pools. While prancing around in swimwear is fine for these particular parts of the ship, you won't be able to wear your swim gear into the dining areas. A costume change will be necessary.

9 No Shorts On Casual Dress Nights In The Dining Area

When you are on a cruise ship, you might be free from work and free from the daily grind, but you are not free from everything. On Royal Caribbean, you still have to wear certain outfits in certain parts of the ship. The dining room refuses guests if they are wearing shorts or tank tops for their evening meal.

8 Keep Camo Off The Islands

Camo wear can be cute and trendy, and lots of people might choose to rock it while exploring port towns. Some Caribbean nations won't be okay with that, though. Camouflage is often reserved for military personnel only. It's always best to check what is deemed acceptable when traveling to a new place.

7 Leave Your Samsung Galaxy Note 7 Phone At Home

The Samsung Galaxy Note 7 telephone has gotten a pretty bad rap for spontaneously overheating, exploding and creating fires. Explosions and fires on cruise ships are terrible news; thus, these personal devices are an absolute no way for both guests of the ship and the crew members who work on them.

6 Drones Can Come, But Only For Land Use

Different cruise lines have different policies where drones are concerned. Royal Caribbean allows guests to bring their favorite drone toy along with them on their vacation, but they won't get to fly it on the ship. It can only be used once the ship docks and travelers head to the port town.

5 No Shaking Hands With The Captain

A viral illness breaking out on a cruise ship can have some pretty dire consequences. In order to minimize the chances of everyone getting ill, some cruise lines have decided that they will no longer allow the guests to shake hands with crew members and the captain. Every ship needs a captain. One down for the count is no good at all.

4 Want To Set A Romantic Scene? You'll Have To Omit The Candles

A raging fire on a cruise ship would be a complete and total disaster. Many items are banned from cruise liners because they are a potential fire hazard. If couples want to embark on the most romantic vacation of their lives, they will have to leave the candles behind. They are not permitted on board.

3 Limit Your Luggage

When traveling with Royal Caribbean, you have to be crafty in what you choose to bring along. It might be tempting to bring every article of clothing and every pair of shoes you own because there is so much to do and see on a cruise. This cruise line allows up to 90kg of luggage.

2 More Than 24 Weeks Pregnant? No Sailing For You

Royal Caribbean wants its guests to be safe at all costs. They have some pretty strict policies when it comes to boarding their ship and pregnancy. They do not want their expecting guests to travel with them if they are more than twenty-four weeks along. If you are heavily pregnant, you'll have to put that cruise vacation on hold.

1 You Must Attend The Safety Seminar

Before you spend your week on a ship living out your wildest dreams, you will have to go over ship safety procedures. These are non-negotiable, and everyone who boards has to get the rundown. If you chose to forego them, you might also be choosing to forego your entire trip!
