Royal Caribbean allows bottled water in your cabin, but with limits

You can bring water onto a Royal Caribbean ship, but the rules depend on where you're bringing it and how much. The cruise line permits passengers to pack bottled water in their checked luggage and carry-on bags when boarding — typically up to 12 standard bottles per person for the duration of the cruise. However, you cannot bring glass bottles of any kind, and water brought onboard counts toward your personal beverage allowance if you have a beverage package.

Once you're in your cabin, you can keep bottled water there and drink it freely. The restriction kicks in if you try to bring outside beverages into the main dining areas, buffets, or pool deck — those spaces are reserved for beverages purchased from the ship or included in your package. This policy exists because Royal Caribbean generates significant revenue from onboard beverage sales, and the cruise line enforces it consistently across its fleet.

Key Takeaways

  • You can pack bottled water in your luggage before boarding, with a typical limit of 12 bottles per person for the entire cruise.
  • Glass bottles of any kind are prohibited; bring plastic or aluminum bottles only.
  • Water in your cabin is yours to drink, but you cannot bring outside beverages into dining rooms, buffets, or pool areas.
  • If you have a beverage package, water brought from home counts against your package allowance, so check your package terms first.
  • Crew members at security will inspect your bags, so pack water where it's straightforward to show during the boarding process.

How much water you can actually bring

Royal Caribbean's official policy allows one case of bottled water per stateroom for the duration of your cruise. In practice, this means roughly 12 standard 16.9-ounce bottles, though the exact number can vary slightly depending on bottle size and the specific ship. The limit applies to the total amount you bring, not per day, so if you're on a seven-day cruise, you're not adding seven cases — you get one case for the whole week.

Pack your water in your checked luggage rather than your carry-on if possible. Checked bags go through the same security screening, but they're less likely to be opened and inspected in detail. If you do pack water in your carry-on, place it where security can easily see it during the bag check at the terminal. Crew members understand that passengers want to bring water and won't give you trouble if it's clearly visible and within the stated limit.

What types of bottles are allowed and what aren't

Plastic and aluminum bottles are fine. Glass bottles — including wine bottles, beer bottles, and glass water bottles — are strictly prohibited and will be confiscated at security. This rule applies even if the bottle is empty. The reason is safety: on a moving ship, glass breaks easily and creates hazards in cabins and common areas.

Collapsible water bottles made from silicone or flexible plastic are allowed and actually a smart choice because they take up less space in your luggage. You can fill them at water fountains and drink stations throughout the ship once you're onboard. Some passengers bring empty collapsible bottles, pack them flat, and fill them after boarding — this is a legal workaround that saves luggage space.

Water in your cabin versus water in public areas

Your cabin is your private space, and you can drink any beverage you brought there without restriction. This includes water, coffee, tea, or any other non-alcoholic drink. You can also request ice from your cabin steward, which you can use to chill water or other drinks in your room.

Public areas are different. You cannot bring outside water into the main dining room, buffet, pool deck, or specialty restaurants. If a crew member sees you with a bottle of outside water in these spaces, they will ask you to return to your cabin or dispose of it. This rule is enforced because the ship wants to direct beverage sales through its own outlets. Tap water from fountains and drink stations throughout the ship is free and safe to drink anywhere, so you're not without options if you finish your brought water.

Beverage packages and how outside water affects them

If you purchase a beverage package — such as the Refreshment Package or Deluxe Beverage Package — water brought from home may count against your package allowance depending on the package type and your specific booking. Some packages include unlimited bottled water, while others do not. Check your booking confirmation or contact Royal Caribbean before your cruise to understand exactly what your package covers.

The safest approach is to assume that outside water counts and plan accordingly. If you have a package that includes unlimited beverages, you likely have unlimited bottled water included anyway, so bringing extra water from home becomes unnecessary. If you don't have a package, the water you bring is genuinely free and won't affect any onboard charges.

Free water sources on the ship

Royal Caribbean provides free tap water throughout the ship. You can get it from water fountains, drink stations in the buffet, and by requesting it at any bar or beverage station — bartenders will give you a cup of water at no charge. This water is safe to drink and comes from the ship's desalination system, which produces fresh water from seawater. Many passengers drink tap water throughout their cruise without issue.

If you prefer bottled water but don't want to pay for it onboard, bringing your own supply from home is the most economical choice. A case of bottled water at a grocery store costs far less than buying individual bottles on the ship, where a single bottle can run $3 to $5 depending on the brand and size.

What happens if you break the water rules

If crew members find outside water in a public dining or pool area, they will confiscate it and ask you to return to your cabin. You won't face a fine or formal penalty for a first offense — the crew's goal is straightforward to enforce the policy. Repeated violations could result in a conversation with guest services, but this is rare.

If you attempt to bring glass bottles or prohibited items, security will catch them during the boarding process and remove them. You won't be allowed to board with glass, so don't try to sneak it through. The screening is thorough, and crew members have seen every workaround passengers attempt.

Frequently Asked Questions

Can I bring a water bottle and refill it at the ship's water fountains?

Yes. Bring an empty reusable bottle and fill it at any water fountain or drink station onboard. This is allowed and actually encouraged by many passengers as an environmentally friendly option. Tap water from the ship's system is safe to drink.

What if I have a medical condition and need more water than the limit allows?

Contact Royal Caribbean's guest services before your cruise and explain your situation. They may grant an exception for medical reasons. Bring documentation if you have it — a letter from your doctor or a prescription that mentions increased water intake — to support your request.

Can I bring water in my carry-on bag when I board?

Yes, water in your carry-on goes through the same security screening as checked bags. Pack it where security can easily see it. The same one-case limit applies whether the water is in your carry-on or checked luggage.

Do I have to pay for water if I don't bring my own?

No. Tap water from fountains and drink stations is free. Bottled water purchased onboard costs extra, but plain water from a cup is always available at no charge. Many passengers use this option throughout their cruise.

Will my water count against my beverage package limit?

It depends on your specific package. Some packages include unlimited bottled water; others do not. Check your booking details or call Royal Caribbean before your cruise to confirm what your package covers. If you're unsure, assume it counts and plan your water supply accordingly.
