Royal Caribbean allows you to bring bottled water aboard, but only unopened bottles in your carry-on luggage during embarkation

You can pack unopened bottled water when you board the ship at the port. Royal Caribbean's policy permits sealed, unopened bottles of water in your carry-on bag as you walk up the gangway. Once you're onboard, you can keep these bottles in your cabin. However, the cruise line does not allow you to bring water through security in checked luggage, and you cannot bring open or partially consumed bottles of any beverage.

The reasoning behind this rule is straightforward: Royal Caribbean provides unlimited tap water at no charge throughout the ship, in dining areas, at the buffet, and from your cabin's plumbing. The restriction on checked luggage exists because the ship's security screening process treats liquids in checked bags the same way airports do — they're screened separately and often confiscated if they exceed certain volumes.

Key Takeaways

  • Unopened bottled water is allowed in your carry-on bag when you board the ship, but not in checked luggage.
  • Tap water throughout the ship is free and safe to drink, including water from your cabin faucet and at all dining venues.
  • You cannot bring open, partially consumed, or reusable bottles filled with water through embarkation security.
  • If you want bottled water during your cruise, you can purchase it onboard at the convenience store or order it through room service.
  • Bringing your own unopened bottles saves money compared to purchasing water on the ship, where a bottle typically costs $3 to $5.

What happens when you board with bottled water

When you arrive at the port terminal, you'll go through a security screening similar to airport security. Your carry-on bags will be X-rayed, and security staff will see your unopened water bottles. Because they are sealed and unopened, they pass through without issue. You then proceed to the gangway and board the ship with your water intact.

Once you're in your cabin, store the bottles in your mini-fridge if you have one, or in a cool spot away from direct sunlight. Many cruisers bring 4 to 6 unopened bottles per person to have cold water available without purchasing it onboard. This is a practical way to reduce your onboard spending, since bottled water sold by Royal Caribbean costs significantly more than what you'd pay at a grocery store before your cruise.

Why tap water is your main water source onboard

Royal Caribbean treats and tests its tap water to meet or exceed U.S. Environmental Protection Agency standards. The ship's water system is regularly monitored, and the water is safe to drink directly from your cabin faucet, from water stations throughout the ship, and from glasses served at meals. You don't need to purchase bottled water to stay hydrated during your cruise.

The ship also provides water fountains and water dispensers in public areas, dining venues, and the buffet. If you prefer cold water, you can request ice water at any bar, restaurant, or from room service at no charge. Many cruisers bring reusable water bottles and fill them throughout the day, which is both economical and environmentally practical.

Purchasing water onboard if you didn't bring any

If you board without bottled water or run out during your cruise, you have two options. The ship's convenience store (usually called the Marketplace or similar) sells bottled water, typically in 16-ounce or 20-ounce sizes. Prices range from $3 to $5 per bottle depending on the ship and current pricing. You can also order water through room service, which delivers it to your cabin, though this method usually carries a delivery charge in addition to the water cost.

Some cruisers purchase a beverage package that includes bottled water, though this is most economical if you plan to buy many drinks throughout your cruise. For water alone, bringing unopened bottles from home remains the most cost-effective choice.

What you cannot bring and why

Do not pack water in your checked luggage. Royal Caribbean's security process screens checked bags separately, and liquids in checked luggage are typically removed during this screening. Even if they make it past screening, you won't have access to checked luggage until you disembark, so there's no practical benefit to packing water there.

You also cannot bring open bottles, partially consumed bottles, or reusable water bottles filled with water through embarkation security. Security staff will ask you to discard any open beverage before you board. Reusable bottles are allowed onboard, but they must be empty when you pass through security — you can fill them with tap water once you're aboard.

Packing water strategically for multi-day cruises

If you're taking a longer cruise, consider how many unopened bottles you can realistically carry in your carry-on bag. A standard carry-on has limited space, and you'll also need room for medications, toiletries, and other essentials. Most cruisers find that bringing 4 to 6 bottles per person is manageable and provides water for the first few days without taking up excessive luggage space.

After you've consumed the water you brought, you can refill a reusable bottle with tap water for the remainder of your cruise. This approach balances the cost savings of bringing some bottled water with the practicality of not overpacking. If you're traveling with family, coordinate with other travelers in your group to avoid everyone bringing the maximum amount.

Frequently Asked Questions

Can I bring a reusable water bottle filled with water through security?

No. Reusable bottles must be empty when you pass through embarkation security. Once you're onboard, you can fill your empty reusable bottle with tap water from your cabin, dining areas, or water fountains throughout the ship. This is a practical solution for staying hydrated without purchasing bottled water.

What if I'm flying to the port and don't want to buy water at the airport?

Bring an empty reusable bottle in your carry-on and fill it at an airport water fountain after you pass through airport security. Then empty it before you board the ship at the port. Once onboard, refill it with tap water. This avoids paying airport prices and ensures you have water available during embarkation.

Are there any restrictions on the size or brand of bottled water I bring?

Royal Caribbean does not specify brand restrictions or maximum bottle sizes in its carry-on policy. Standard single-serve bottles (16 to 20 ounces) are the most practical to pack. Avoid bringing very large bottles or cases, as they take up excessive carry-on space and may not fit comfortably in your bag alongside other necessities.

Do I need to declare the water bottles when I board?

No declaration is necessary. Your carry-on bags go through X-ray screening just like at an airport, and unopened water bottles are visible on the scan. Security staff will see them and allow them through without requiring you to mention them separately.

Can I bring water if I'm boarding at a different port during a repositioning cruise?

Yes, the same rules explore at any port where you board a Royal Caribbean ship. Unopened bottled water is allowed in your carry-on during embarkation security at any port. However, if you're joining the ship at a port other than the home port, you may have less time to shop beforehand, so planning ahead is especially important.
