Yes, you are allowed to bring vapes and e-cigarettes on a Royal Caribbean cruise in 2026, but their use is strictly regulated. You can pack your vape device in your carry-on luggage (never in checked bags due to the lithium-ion battery fire risk), but you are prohibited from using it in your stateroom, on your private balcony, or in most public indoor areas. Royal Caribbean treats vaping exactly like tobacco smoking; it is only permitted in designated smoking areas, which are typically located on one side of an outdoor deck or in a specific corner of the casino. Violating this policy—especially vaping in your room—can result in a $250 to $500 cleaning fee and potential removal from the ship. Furthermore, as of 2026, many Caribbean destinations like Mexico and certain island nations have implemented strict bans on the import of vapes. While you can have it on the ship, taking it off in a port of call where it is illegal could lead to confiscation or even arrest by local authorities, so it is vital to check the laws of each specific country on your itinerary.
